Extracting the Domain from the URL using ColdFusion - coldfusion

I am currently using CGI variables to extract the full URL and the hostname from the current URL:
<cfset currentURL = CGI.SERVER_NAME>
<cfset host = ListFirst(currentURL, ".")>
The previous code works as expected.
I would like to also extract the domain. I can't find a CGI variable for that surprisingly, and I have tried the following code but it does not seem to work:
<cfset domain = ListLast(currentURL, "#host#")>
But the domain variable is only showing 'om' instead of 'domain.com' when I output it. What am I doing wrong here?

This is one way to do it and it will handle domains with multiple subdomain parts (e.g., local.dev.mydomain.com).
<cfset currentURL = CGI.SERVER_NAME>
<cfset domainParts = listLen(currentURL, ".")>
<cfset domain = gettoken(currentURL,domainParts-1,".") & "." & gettoken(currentURL,domainParts,".") >

The full URL would be:
'#getPageContext().getRequest().getScheme()#://#cgi.server_name#/#cgi.script_name#?#cgi.query_string#'
That will include protocol, path, and url variables.
The domain name is simply #cgi.server_name#.

Coldfusion cflocation strange behavior

I am storing a google review URL in my database as:
https://www.google.com/search?CFID=ac59cfdf-bbad-4017-9759-e88054f3f242&CFTOKEN=0&q=njcomputerrepair%2Bbrick%2Bnj&oq=njcomp&aqs=chrome.1.69i60j69i59j69i60j69i57j0l2.2762j0j9&sourceid=chrome&ie=UTF-8#lrd=0x89c18348735c2907:0x59aa614832a36b22,3,
And then in my application I set that URL to a variable and I redirect the user to that URL using cflocation.
<cfquery name="geturl" datasource="#datasource#">
select (residential_ReviewURL) as redirectURL
from subscribers
</cfquery>
<!--- Redirect to main html redirect page --->
<cfoutput>
<cflocation url="#getURL.redirectURL#">
</cfoutput>
However the URL gets changed at some point because I think that Coldfusion doesn't like the characters in the URL and it replaces them with % or removes them. Therefore when the user hits the google page, the page doesn't process as it should.
Here is how the URL looks after the redirect:
https://www.google.com/search?CFID=ac59cfdf-bbad-4017-9759-e88054f3f242&CFTOKEN=0&CFID=ac59cfdf-bbad-4017-9759-e88054f3f242&CFTOKEN=0&q=njcomputerrepair%2Bbrick%2Bnj&oq=njcomp&aqs=chrome.1.69i60j69i59j69i60j69i57j0l2.2762j0j9&sourceid=chrome&ie=UTF-8#lrd%3D0x89c18348735c2907%3A0x59aa614832a36b22%2C3%2C
How can I stop ColdFusion from changing the URL and keep id exactly as how it is stored in the database?
UPDATE
So I found that URLdecode will preserve the string. Here is what I have.
#urlDecode(getURL.redirectURL)#
The output is as follows
https://www.google.com/search?CFID=ac59cfdf-bbad-4017-9759-e88054f3f242&CFTOKEN=0&q=njcomputerrepair+brick+nj&oq=njcomp&aqs=chrome.1.69i60j69i59j69i60j69i57j0l2.2762j0j9&sourceid=chrome&ie=UTF-8#lrd=0x89c18348735c2907:0x59aa614832a36b22,3,
Why is it adding CFID and CFTOKEN to the URL though? I have it turned off in my Application.CFM:
<cfapplication name="yaya"
clientmanagement="no"
sessionmanagement="no"
setclientcookies="no"
setdomaincookies="no"
sessiontimeout="#CreateTimeSpan(0,2,0,0)#"
applicationtimeout="#CreateTimeSpan(1,0,0,0)#"
>
To help others coming here:
cflocation have a parameter addToken which needs to set to no if we do not want to add CFID and CFTOKEN to the generated URL.

URL Rewrite with IIS using ColdFusion

I've done a bit of searching but just can't put it all together. Here's what I need:
I'd like someone to surf to:
www.mysite.com/thisPlace
and have it redirect them to
www.mysite.com/template.cfm?pm=ms&loc_id=4
To do so, I somehow need to capture that they didn't request an existing file in their http request and run a .cfm page that queried the database for a record where locationName = 'thisPlace' and then redirect them to a page like
template.cfm?pm=ms&loc_id=4, where 4 is the record id of the row that matched 'thisPlace'
If your default document in IIS is set to index.cfm you could create a folder (directory) called "thisPlace" and place an index.cfm file that contains nothing but a <cflocation> tag and the accompanying query/logic to figure the URL.
Website.com/thisPlace would then function as you describe.
Edit:
You could add a custom 404 page...
Make it a .cfm file instead of html. Scan the template path to see what the user is looking for. If you find it in your database, redirect them there, else redirect them to a general 404 page.
<!---Up to a certain point (the directory in which you store your code) this will always be the same so you can hard-code your number --->
<cfset QueryConstant = #LEFT(CGI.CF_Template_Path, 22)#>
<!---Find the overall length of the template path. --->
<cfset QueryVariable = #Len(CGI.CF_Template_Path)#>
<!---Take whatever is past your QueryConstant (AKA the string that produces a 404 error.) --->
<cfset theRightNumber = QueryVariable - 22>
<cfset QuerySearchString = #RIGHT(CGI.CF_Template_Path, theRightNumber)#>
<cfquery name="ListOfLocations" datasource="CRM">
SELECT TOP 1 LocationID
FROM LocationTable
WHERE LocationName LIKE '%#QuerySearchString#%'
</cfquery>
<cfif ListOfLocations.recordcount>
<cflocation url="/SomePage.cfm?LocationID=#ListOfLocations.LocationID#">
<cfelse>
<cflocation url="/Regular404page.html">
</cfif>
Thanks guys! Huge help! Using your inputs, here's what I did:
(had to use QUERY_STRING instead of CF_Template_Path, as CF_Template_Path did not pass along anything after the url of the custom error page.
I set up a custom 404 error Execute URL in IIS to a file named check404error.cfm.
When someone looks for www.example.com/thisPlace, IIS sends them to http://www.example.com/check404error.cfm. I use the CGI.QUERY_STRING (404;http://www.example.com:443/thisPlace) to ultimately get the "thisPlace" string to search with.
<!---Up to a certain point (the directory in which you store your code) this will always be the same so you can hard-code your number --->
<cfset QueryConstant = #LEFT(CGI.QUERY_STRING, 31)#>
<!---Find the overall length of the template path. --->
<!---31 is the length of '404;http://www.example.com:443/' --->
<cfset QueryVariable = #Len(CGI.QUERY_STRING)#>
<!---Take whatever is past your QueryConstant (AKA the string that produces a 404 error.) --->
<cfset theRightNumber = QueryVariable - 31>
<cfset QuerySearchString = #RIGHT(CGI.QUERY_STRING, theRightNumber)#>
<cfquery name="ListOfLocations" datasource="#request.dsn#">
SELECT location.id
FROM location WHERE url_name = <cfqueryparam value="#QuerySearchString#" cfsqltype="CF_SQL_VARCHAR" maxlength="255"> LIMIT 1
</cfquery>
<cfif ListOfLocations.recordcount>
<cflocation url="https://example.com/template.cfm?pm=ms&loc_id=#ListOfLocations.id#" addtoken="no" statusCode="301">
<cfelse>
<cflocation url="/404error.cfm" addtoken="no">
</cfif>
This is how most popular MVC Framework work today, by parsing out the URL segments.
Do you have access to any kind of URL rewrite software?
Since you are using IIS it has a built in rewrite engine where you could simply rewrite these kind of requests to a known file saving you the overhead of sending a 404 reply and parsing that out and having more request created as a result of that.
See http://wiki.coldbox.org/wiki/URLMappings.cfm for details. We use the Isapi rewrite version version to do just what you are asking for
Receive request for www.mysite.com/thisPlace
thisPlace isn't a directory
thisPlace isn't a file
Resend to index.cfm or a location of your chosing for additional parsing
Helicon Rewrite sends an HTTP header named HTTP_X_REWRITE_URL with the original requested URL so parsing it out is then very easy.
This all happens inline withing the one request so the client is never redirected.

Dynamic Subdomains - ColdFusion 11

Anyone know a way to create dynamic subdomains in coldfusion 11 without having to add them to a dns server?
I want to be able to redirect each of my clients in a personalized subdomain every time they log in to my system.
ex: client1.example.com client2.example.com
This works if your site is hosted in a Windows IIS server.
If you are using IIS then the following can help you. Use loops and conditions as your requirements.
<!--- Provide you IIS SiteName --->
<cfset siteName = "Your IIS Site Name">
<!--- Your new domain address --->
<cfset newSiteBinding = "client2.example.com">
<!--- your port address --->
<cfset newSitePort = 80>
<cfset fileID = createUUID()>
<cfsavecontent variable="ex"><cfoutput>cd %windir%\system32\inetsrv
%windir%\system32\inetsrv\APPCMD set site /site.name: #siteName# /+bindings.[protocol='http',bindingInformation='*:#newSitePort#:#newSiteBinding#']</cfoutput>
</cfsavecontent>
<cffile action = "write"
file = "E:\#fileID#.bat"
output = "#ex#"
/>
<cfexecute name="E:\#fileID#.bat"
arguments="/c set"
variable="data"
timeout="10"
/>
<cffile action = "delete"
file = "E:\#fileID#.bat"
>
What we are basically doing is that we are creating a .bat file and executing it using cfexecute. Please note that you need to be careful with the paths because the Directory structure might be different in your server.
.BAT file content Example
cd %windir%\system32\inetsrv
%windir%\system32\inetsrv\APPCMD set site /site.name: example /+bindings.[protocol='http',bindingInformation='client2.example.com:80:*']
How the command works. Notice the + at /+bindings?
That means adding a new binding and /-bindings tries to remove an existing binding.

How to access the URL parameter id in Coldfusion if it's after a hashtag #?

After trying for about an hour without success... (coldfusion8) a dummy question, but I*m stuck:
My URL (Jquery Mobile, no pushstate, that's why it looks like it is):
http://www.page.de/test/mem/search.cfm#/test/mem/search.cfm?id=9900000003869
If I output:
<cfdump output="e:\website\dump.txt" label="catch" var="#url#">
I get this:
catch - struct
ID: 9900000003869
But how do i access it... I'm trying forever, nothing works:
<cfdump output="e:\website\dump.txt" label="catch" var="#id#">
<cfdump output="e:\website\dump.txt" label="catch" var="#ID#">
<cfdump output="e:\website\dump.txt" label="catch" var="#url.id#">
<cfdump output="e:\website\dump.txt" label="catch" var="#url.ID#">
<cfdump output="e:\website\dump.txt" label="catch" var="#StructGetValue(url,"id")d#">
...
Thanks for helping!
Ok... This works:
URL = http://www.page.de/test/mem/search.cfm#/test/mem/search.cfm?id=9900000003869
<cfset objRequest = GetPageContext().GetRequest() />
<cfset strUrl = right( objRequest.GetRequestUrl().Append( "?" & objRequest.GetQueryString() ).ToString(), 13)>
Credit
If someone finds an easier, please post. I will check as answer.
You're trying to read this from a txt file?
Can you not simply use:
<cfdump label="catch" var="#url.id#" />
Does that work?
EDIT:
Could you try capturing and formatting what you need first then after, writing it to the file?
For example, try using:
<cfsavecontent variable="myFileContents">
<cfoutput>#url.id#</cfoutput>
</cfsavecontent>
<cffile action="Write" file="e:\website\dump.txt" output="#myFileContents#" />
I have not tested this code, but give it a go and see!
Might want to put a check on that URL variable too using isDefined()
Good luck.
Doing some research on fragment identifiers (which is a new term to me :( )prompted by Peter and Duncan's comments, I've found from wiki: http://en.wikipedia.org/wiki/Fragment_identifier
The fragment identifier functions differently than the rest of the
URI: namely, its processing is exclusively client-side with no
participation from the server — of course the server typically helps
to determine the MIME type, and the MIME type determines the
processing of fragments. When an agent (such as a Web browser)
requests a resource from a Web server, the agent sends the URI to
the server, but does not send the fragment. Instead, the agent waits
for the server to send the resource, and then the agent processes the
resource according to the document type and fragment value.
now, being your client IS sending the fragment and the url variable is accessible to you for some reason, using it is done by my original post to follow.
<cfoutput>
is generally how you output a variable or other evaluations to the screen.
<cfset myName = "Travis">
<cfoutput>Hello, my name is #myName#</cfoutput>
You can also access the variable by using it in a statement that doesn't output anywhere.
<cfset myFullName = myName & " Mak">
You can also use the variables in a query
<cfquery name = "qSomeQuery" datasource = "#application.dsn#">
select * from table where id = #url.id#
</cfquery>
However, that's the bad way to use it in a query, you should always use cfquery param.
<cfquery name = "qSomeQuery" datasource = "#application.dsn#">
select * from table where id = <cfqueryparam cfsqltype="cf_sql_integer" value="#url.id#">
</cfquery>
The problem you're having in testing the variable is due to incorrect syntax.
<cfif isDefined("url.id")> verses <cfif isDefined(url.id)> a more accurate test is <cfif structKeyExists(url, "id")>
For some reason my CF server truncates everything in the url after the # but yours doesn't seem to have this problem. As your cfdump states, you can see your url variables so "accessing" the url variable is as easy as using it: #url.id# or testing it <cfif isDefined("url.id")>

Using <cfinclude> with this.mapping

In my application I have a header and footer include. In my Application.cfc I've set up a function that names my application and sets mapping.
<cfcomponent output="no">
<cfset this.name = "thesitename">
<cfset this.datasource = "thesitedatasource">
<cfset this.rootDir = getDirectoryFromPath(getCurrentTemplatePath()) />
<cfset this.mappings = structNew()>
<cfset this.mappings["/planning"] = "#this.rootDir#planning/" />
<cfset this.mappings["/images"] = "#this.rootDir#images/" />
<cfset this.mappings["/includes"] = "#this.rootDir#includes/" />
<cfset this.mappings["/js"] = "#this.rootDir#js/" />
<cfset this.mappings["/portfolio"] = "#this.rootDir#portfolio/" />
</cfcomponent>
If I have a page in a subdirectory like this: planning/index.cfm the <cfinclude> can't locate anything in the images folder when I use the following path: <li class="imagelink"><img src="/images/facebook.png"></li>
Pages in the root directory don't have a problem.
If I understand correctly, the problem has to do with the mapping doesn't take place prior to the include being called, or something like that... How do I get the mapped paths to work properly in my include?
ColdFusion mappings are completely separate from a web server 'alias' or 'virtual directory'. In order for your code to work, you will need to add a web server mapping, 'alias' in Apache or 'virtual directory' in IIS, named 'images' that points to the directory where you keep the images.
The 'images' ColdFusion mapping will only work in ColdFusion - for example, when creating an object, you could use createObject( "component", "images.image") (assuming of course that you had a CFC named Image in that diectory.
