I want to use apache rewrite module to do complex rewriting.
For example
If the url is http://www.site.com/wall and http://www.site.com/profile and http://www.site.com/info I want to rewrite into http://www.site.com/gotopage.php?page=wall ,or http://www.site.com/gotopage.php?page=profile and so forth
But if the url is other than that I want to pass it the other way
For example. if the url is http://www.site.com/newthing then it should rewrite as http://www.site.com/index.php?params=newthing
Please Help. I tried to see other questions but did not get it!
RewriteEngine On
# Special rule for 3 unique cases
RewriteRule /(wall|profile|info)$ /gotopage.php?page=$1 [L]
# Only rewrite if the URL has not yet been rewritten
RewriteCond %{HTTP_URL} (?!gotopage\.php|index\.php)
RewriteRule /([^/]+) /index.php?params=$1 [L]
Here's an explanation, line by line:
Any URL that matches one of the 3 specified words gets rewritten to go to gotopage.php.
This line is a condition for the next line. Only if the URL matches this regex will the next line even be considered. The regex checks to ascertain that the request is not already going to gotopage.php or index.php. If it is, we don't want to rewrite anything (we would just end up in an infinite loop).
If the requested URL has no subsequent slashes, rewrite it to go to index.php.

I need to convert with HTACCESS method tons of URL's allready produced (and already indexed...) by Wordpress for articles containing folders/subfolders to simples URL's without any folder/subfolder name.
Example:
FROM https://www.website.com/Animals/Cats/mycat.html TO https://www.website.com/mycat.html
FROM https://www.website.com/Animals/Dogs/mydog.html TO https://www.website.com/mydog.html
FROM https://www.website.com/Countries/France/bordeaux.html TO https://www.website.com/bordeaux.html
etc...
I already changed permalinks options in Wordpress config. So, now URL's produced are in the good format (Ex: https://www.website.com/bordeaux.html) without any folder name.
My problem is to redirect all OLD Url's to this new format to prevent 404 and preserve the rank.
If tryed to add in my .htacess this line :
RewriteRule ^/(.*)\.html$ /$1 [R=301,L,NC]
I egally tryed RedirectMatch 301 (.*)\.html$ method and it's the same. I'm going crazy with this.
What am i doing wrong and could you help me?
Thanks
RewriteRule ^/(.*)\.html$ /$1 [R=301,L,NC]
The URL-path matched by the RewriteRule pattern never starts with a slash. But you can use this to only match the last path-segment when there are more "folders". And the target URL also needs to end in .html (as per your examples).
So, this can be written in a single directive:
RewriteRule /([^/]+\.html)$ /$1 [R=301,L]
This handles any level of nested "folders". But does not match /foo.html (the target URL) in the document root (due to the slash prefix on the regex), so no redirect-loop.
(No need for any preceding conditions.)
Here the $1 backrefence includes the .html suffix.
Just match the last part of the url and pass it to the redirect:
RewriteRule /([^/]+)\.html$ /$1.html [R=301,L,NC]
It will match any number of directories like:
https://www.website.com/dir1/page1.html
https://www.website.com/dir1/dir2/page2.html
https://www.website.com/dir1/dir2/dir3/page3.html
https://www.website.com/dir1/dir2/dir3/dir3/page4.html
I am using IBM HTTP server configuration file to rewrite a URL redirected from CDN.
For some reason the URL comes with a superfluous single question mark even when there are no any query string. For example:
/index.html?
I'm in the process of making the 301 redirect for this. I want to remove the single "?" from the url but keep it if there is any query string.
Here's what I tried but it doesn't work:
RewriteRule ^/index.html? http://localhost/index.html [L,R=301]
update:
I tried this rule with correct regular expression but it never be triggered either.
RewriteRule ^/index.html\?$ http://localhost/index.html [L,R=301]
I tried to write another rule to rewrite "index.html" to "test.html" and I input "index.html?" in browser, it redirected me to "test.html?" but not "index.html".
You need to use a trick since RewriteRule implicitly matches against just the path component of the URL. The trick is looking at the unparsed original request line:
RewriteEngine ON
# literal ? followed by un-encoded space.
RewriteCond %{THE_REQUEST} "\? "
# Ironically the ? here means drop any query string.
RewriteRule ^/index.html /index.html? [R=301]
Question-mark is a Regular Expression special character, which means "the preceding character is optional". Your rule is actually matching index.htm or index.html.
Instead, try putting the question-mark in a "character class". This seems to be working for me:
RewriteRule ^/index.html[?]$ http://localhost/index.html [L,R=301]
($ to signify end-of-string, like ^ signifies start-of-string)
See http://publib.boulder.ibm.com/httpserv/manual60/mod/mod_rewrite.html (for your version of Apache, which is not the latest)
Note from our earlier attempts, escaping the question-mark doesn't seem to work.
Also, I'd push the CDN on why that question-mark is being sent. This doesn't seem a normal pattern.
I am using Apache 2.4.7. I use mod_rewrite to alter some urls.
I want to rewrite http://example.com/servicename/oldpage?id=abcto http://example.com/servicename/newpage.
Other similar rewrites work so I belive the ? inside url is causing problems.
I have tried escaping it with \.
This works as there is no ? in url:
RewriteRule ^/servicename/old /servicename/new
But these don't work:
RewriteRule ^/servicename/oldpage?id=abc /servicename/newpage
RewriteRule ^/servicename/oldpage\?id=abc /servicename/newpage
I have also tried using RewriteCond from examples like this: .htaccess rewrite URL with a question mark "?" but I didn't manage to get them work.
How should rewrite url that contains question mark?
EDIT: I tried solutions given in Match Question Mark in mod_rewrite rule regex but was not able to make them work for me. That question is about preserving query string when rewrite while I want to remove it when rewriting.
RewriteRule pattern is matched against the part of the URL after the hostname and port, and before the query string.
When the requested URI contains a query string, and the target URI does not, the default behavior of RewriteRule is to copy that query string to the target URI. Using the [QSD] flag causes the query string to be discarded.
So, this should work:
RewriteRule ^/servicename/oldpage /servicename/newpage [QSD]
I have such a url:
/keyword1/keyword2/slugged-title-8286-1.jpg?wx=292&hx=164
I would like to forward in this case to:
/images/8286-1.jpg?wx=292&hx=164
the listing number (here 8286) can be 4 or 5 digits and could perhaps contain letters. Also the parameters after ? could be different.
Could you please help me to get this solved?
I haven't done a lot with regex and not sure how this can be done.
You can use this rule in your site root .htaccess:
RewriteEngine On
RewriteRule -(\w+(?:-\d+)?\.jpe?g)$ /images/$1 [L,NE,R=302]
If you don't want a full redirect then use:
RewriteRule -(\w+(?:-\d+)?\.jpe?g)$ /images/$1 [L]
QUERY_STRING is automatically carried over to target URL.
I am using Microsoft-IIS/7.5 on a hosted server (Hostek.com)
I have an existing site with 2,820 indexed links in Google. You can see the results by searching Google with this: site:flyingpiston.com Most of the pages use a section, makerid, or bikeid to get the right information. Most of the links look like this:
flyingpiston.com/?BikeID=1068
flyingpiston.com/?MakerID=1441
flyingpiston.com/?Section=Maker&MakerID=1441
flyingpiston.com/?Section=Bike&BikeID=1234
On the new site, I am doing URL rewriting using .htaccess. The new URLs will look like this:
flyingpiston.com/bike/1068/
flyingpiston.com/maker/1123/
Basically, I just want to use my htaccess file to direct any request with a "?" question mark in it directly a coldfusion page called redirect.cfm. On this page, I will use ColdFusion to write a custom 301 redirect. Here's what ColdFusion's redirect looks like:
<cfheader statuscode="301" statustext="Moved Permanently">
<cfheader name="Location" value="http://www.newurl/bike/1233/">
<cfabort>
So, what does my htaccess file need to look like if I want to push everything with a question mark to a particular page? Here's what I have tried, but it's not working.
RewriteEngine on
RewriteRule ^? /redirect.cfm [NS,L]
Update. Using the advice from below, I am using this rule:
RewriteRule \? /redirect/redirect.cfm [NS,L]
To try to push this request
http://flyingpiston2012-com.securec37.ezhostingserver.com/?bikeid=1235
To this page:
http://flyingpiston2012-com.securec37.ezhostingserver.com/redirect/redirect.cfm
There's a couple of reasons what you're trying isn't working.
The first one is that RewriteRule uses a regex, and ? is a regex metacharacter, which therefore needs be escaped with a backslash (\?) to tell it to match the literal question mark character.
However, the second part of the problem is that the regex for RewriteRule is only tested against the filename part of the URL - it specifically excludes the query string.
In order to match against the query string you need to use the RewriteCond directive, placed on the line before the rule (but applied in between the RewriteRule matching and replacing), acting as an additional filter. The useful bit is that you can specify which part of the URL to match against (as well as having the option for using non-regex tests).
Bearing all this in mind, the simplest way to match/rewrite a request with a query string is:
RewriteCond %{QUERY_STRING} .
RewriteRule .* /redirect/redirect.cfm
The %{QUERY_STRING} is what the regex is tested against (everything in CF's CGI scope can be used here, and some other stuff too - see the Server Variables box in the docs).
The single . just says "make sure the matched item has any single character"
At the moment, this rule will preserve the existing query string - if you want to discard it, you can place a ? onto the end of the replacement URL. (If you need to use a query string on the URL and not discard the old version, use the [QSA] flag.)
In the opposite direction, you're losing the filename part of the URL - to preserve this, you probably want to append it onto the replacement as PATH_INFO, using the automatic whole-match capture $0.
These two things together provides:
RewriteCond %{QUERY_STRING} .
RewriteRule .* /redirect/redirect.cfm/$0?
One final thing is that you'll want to guard against infinite loops - the above rule strips the query string so it will always fail the RewriteCond, but better to be safe (especially if you might need to add a query string), which you can do with an extra RewriteCond:
RewriteCond %{QUERY_STRING} .
RewriteCond %{REQUEST_URI} !/redirect/redirect\.cfm
RewriteRule .* /redirect/redirect.cfm/$0?
Multiple RewriteCond are combined as ANDs, and the ! negates the match.
You can of course add whatever flags are required to the RewriteRule to have it behave as desired.
