MOD_REWRITE is not behaving as expected - regex

This doesn't work:
RewriteRule ^([^/]+)([/]?)$ /index.cgi?l=$1 [NC,L]
This doesn't work:
RewriteRule ^([^/]+)/?$ /index.cgi?l=$1 [NC,L]
There's no other rules in the .htaccess file. Here's the complete version:
Options -Indexes
Options ExecCGI
AddHandler cgi-script .cgi .pl .q
ErrorDocument 500 /error500.cgi
ErrorDocument 404 /error404.cgi
Options +FollowSymlinks
RewriteEngine On
RewriteBase /
RewriteRule ^([^/]+)/?$ /index.cgi?l=$1 [NC,L]
This DOES work, but it's not what I want.
RewriteRule ^([^/]+)/([^/]+)$ /index.cgi?l=$1&a=$2 [NC,L]
I want both the first slash and second directory to be optional. Why won't the question mark match 0 or 1 instances like it's supposed to? I am freaking here...

By using a $, you're specifying that it's the end of the text, so that won't match anything after a /. (in regex, ^ specifies the beginning of a string and $ specifies the end)
You could remove the $, then it will make the second parameter optional - that sounds like what you're looking for.
Try this to see if your mod_rewrite is working correctly:
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [R,L]

RewriteRule with optional parameter for redirection in .htacces

I would like to rewrite from:
www.domain.de/123/hello
to:
www.domain.de/index.php?a=$1&b=$2
I have this rule:
RewriteEngine On
Options +FollowSymlinks
RewriteBase /
RewriteRule ^([^/]+)/([^/]+)?$ index.php?a=$1&b=$2 [L,QSA,NC]
it works fine. But I also would like that it also works with the input:
www.domain.de/123
(Here I will get an 404 error.)
The &b shout be empty in this case.
How to achive this?
You may use these rules with an optional match for 2nd paramter:
RewriteEngine On
Options +FollowSymlinks
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)(?:/([^/]+))?/?$ index.php?a=$1&b=$2 [L,QSA]
Here (?:/([^/]+))? is an optional match to make sure above rule matches both:
www.domain.de/123/hello
and
www.domain.de/123

htaccess clean urls & replacing whitespaces and %20 with -

I'm strugling to make this work. At the moment my htaccess contains the following code:
#Debugging - Error reporting
php_flag display_startup_errors on
php_flag display_errors on
php_flag html_errors on
#Commpression
<ifmodule mod_deflate.c="">
<filesmatch ".(js|css|html|png|jpg|jpeg|swf|bmp|gif|tiff|ico|eot|svg|ttf|woff|pdf)$"="">
SetOutputFilter DEFLATE
</filesmatch>
</ifmodule>
Options All -Indexes +FollowSymLinks -MultiViews
<IfModule mod_rewrite.c>
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /
#RewriteCond %{THE_REQUEST} (\s|%20)
RewriteRule ^([^\s%20]+)(?:\s|%20)+([^\s%20]+)((?:\s|%20)+.*)$ $1-$2$3 [N,DPI]
RewriteRule ^([^\s%20]+)(?:\s|%20)+(.*)$ /$1-$2 [L,R=301,DPI]
#RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !^.*\.(png|jpg|bmp|gif|css|js)$ [NC]
RewriteRule ^([^/]+/?.+)$ /index.php?req=$1 [L,QSA]
</IfModule>
Everything works great except 1 thing if I try this url for example:
http://www.domain.com/ test/
the browser translates it like to: http://www.domain.com/%20test/
basically after the domain if the path starts with a whitespace or a %20 it fails.
can anyone please point to a solution where the starting spaces will be removed ?
UPDATE
The goal:
www.domain.com/ this is a test / hello there /
or
www.domain.com/ this is a test
to
www.domain.com/this-is-a-test/ or www.domain.com/this-is-a-test/hello-there
I am guilty of writing that code more than 2 years back :P
That can be hugely simplified by this code:
# remove spaces from start or after /
RewriteRule ^(.*/|)[\s%20]+(.+)$ $1$2 [L]
# remove spaces from end or before /
RewriteRule ^(.+?)[\s%20]+(/.*|)$ $1$2 [L]
# replace spaces by - in between
RewriteRule ^([^\s%20]*)(?:\s|%20)+(.*)$ $1-$2 [L,R]
PS: Must add that you need to fix the source of these URLs also because it is really not normal to be getting URLs like this.
This is works fine
<IfModule pagespeed_module>
ModPagespeed on
ModPagespeedEnableFilters collapse_whitespace,remove_comments

Htaccess - replace .html with a forward slash

I want to redirect URLs of this form:
/page.html?variable=value&othervar=true&thirdvar=100
To this:
/page/?variable=value&othervar=true&thirdvar=100
So basically I just want to replace the .html in the middle of the URL with a forward slash, but I need to preserve the get string that comes with it. This is what I tried:
RewriteRule ^page.html(.+)$ /page/$1 [L,R=301]
But this doesn't appear to be working for me. I've made similar things work recently but I can't figure out what I'm missing here. Thanks for any input.
Enable mod_rewrite and .htaccess through httpd.conf and then put this code in your .htaccess under DOCUMENT_ROOT directory:
Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /
# external redirect from /example.html to /example
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+([^.]+)\.html [NC]
RewriteRule ^ /%1/ [R=301,L]
# internal forward from /example/ to //example.html
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-l
RewriteCond %{DOCUMENT_ROOT}/$1.html -f
RewriteRule ^(.+?)/?$ /$1.html [L]

ExpressionEngine mod_rewrite Rule to Redirect URLs with Underscores to Dashes

I'm using ExpressionEngine as my CMS and would like to remove underscores from my site's URLs and replace them with dashes.
For example, I've got a URL that is formatted like this:
http://example.com/index.php/menu/friday-lunch
To remove index.php from the URL, I'm using the following mod_rewrite rule:
RewriteCond $1 !\.(gif|jpe?g|png)$ [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
Which works, since I can just type in: http://example.com/menu/friday-lunch
On the old site I used underscores instead of hyphens for page URIs, so I wrote a mod_rewrite rule to to redirect URIs with underscores to use dashes.
So friday_lunch becomes friday-lunch using the following RewriteRule:
RewriteRule ^([^_]*)_([^_]*_.*) $1-$2 [N]
RewriteRule ^([^_]*)_([^_]*)$ /$1-$2 [L,R=301]
This rule works rather well, except that it 301 Redirects to example.com/index.php/menu/friday-lunch instead of example.com/menu/friday-lunch — notice the addition of index.php.
Here's the entire .htaccess I'm currently using:
<IfModule mod_rewrite.c>
RewriteEngine On
# Removes index.php
RewriteCond $1 !\.(gif|jpe?g|png)$ [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
RewriteRule ^([^_]*)_([^_]*_.*) $1-$2 [N]
RewriteRule ^([^_]*)_([^_]*)$ /$1-$2 [L,R=301]
</IfModule>
How can I redirect all of my URLs with underscores to the equivalent with dashes?
Bonus: to make matters worse, URLs that lead to /system, must not be rewritten with a hyphen, e.g.: example.com/system/login_in/.
Here's a complete set of RewriteRules that should do what you need:
<IfModule mod_rewrite.c>
# Enable Apache's RewriteEngine
RewriteEngine On
# Ignore Matching Directories
RewriteRule ^(images|themes|system) - [L,NC]
# Replace Underscores with Dashes
RewriteRule ^([^_]*)_([^_]*)_(.*)$ /$1-$2-$3 [R=301,L]
RewriteRule ^([^_]*)_(.*)$ /$1-$2 [R=301,L]
# Remove index.php from ExpressionEngine URLs
RewriteCond $1 !\.(gif|jpe?g|png)$ [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]
</IfModule>
To have your mod_rewrite rules ignore the ExpressionEngine system folder and not replace underscores _ with dashes - use the following:
RewriteRule ^(images|themes|system) - [L,NC]
Dissecting the RewriteRule into plain English:
The - flag instructions Apache to do nothing, and to not rewrite the URI
The L flags means this should be last rule; ignore everything following
The NC flag means no-case (so "System" or "SYSTEM" is also matched)
This "ignore" rule is especially important and you may need to add additional directories to exclude depending on your directory structure.
Otherwise, you may end up with images and other files saved with underscores that get replaced with dashes.
Note: If your URLs contain more than three underscores, you'll need to add another RewriteRule above the existing ones for each Word Separator for URL Titles you want to replace:
RewriteRule ^([^_]*)_([^_]*)_(.*)_(.*)_(.*)$ /$1-$2-$3-$4-$5 [R=301,L]
RewriteRule ^([^_]*)_([^_]*)_(.*)_(.*)$ /$1-$2-$3-$4 [R=301,L]
You included 'index.php' in your replacement string.
RewriteRule ^(.*)$ index.php/$1 -> RewriteRule ^(.*)$ $1

HTACCESS redirection with a word replacement in url

I'm having trouble with this reg expression which i belive is correct, but it is not working.
What im trying to do is redirect bunch of urls containing a specific string like this:
http://www.example.com/**undesired-string**_another-string to http://www.example.com/**new-string**_another-string
and
http://www.example.com/folder/**undesired-string**/another-string to http://www.example.com/folder/**new-string**/another-string
So i have this code in the .htaccess:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule (.+)+(undesired-string)+(.+) $1new-string$2 [R=301,L]
</IfModule>
This should replace ANY undesired-string in any url to new-string, but it is not working, any idea why ?
Thank you
Marwen: Try this:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^(.*)undesired-string(.*)$ yoursite.com/$1new-string$2 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
RewriteCond %{HTTP_HOST} !^www.yoursite.com$ [NC]
RewriteRule ^(.*)$ yoursite.com//$1 [L,R=301]
</IfModule>
In your 'updated' code in the comments above, you had it applying the rewrite condition to the undesired-string... So if the actual file or directory was valid it would not rewrite...
Doing this though will always rewrite the undesired-string with new-string - even if its a file name... If that is fine or what you want then all you had to do was move your rewrite conditions to below the rewrite rule...
also.. Just an fyi.. If everything is on yoursite.com you dont need to list yoursite.com
i.e.
yoursite.com/$1new-string$2
just needs to be
/$1new-string$2
which does the same thing: rewrites to the base directory of yoursite.com
now if they are going from mysite.com to yoursite.com then you woulud want to include the domain name because you are redirecting across domain names
Edit: You may also want to use:
[QSA,L,R=301]
instead of just [L,R=301]
Your regex is not really correct. Try:
RewriteRule ^(.*)undesired-string(.*)$ $1new-string$2 [R=301,L]
Or if this doesn't work, try:
RewriteRule ^(.*)undesired-string(.*)$ http://yoursite.com/$1new-string$2 [R=301,L]
Explanation:
^ marks the beginning; $ marks the end; the first (..) goes to $1, the second (..) goes to $2 and so on; * is 0 or more chars; + is 1 or more chars.
To answer my own question. Laravel already redirects the trailing slashes. Problem was that Laravel was installed into a sub-directory. I added the location of the sub-directory to the redirect. My location in this case is: "/lumen/public/". See the fixed htaccess below.
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>
RewriteEngine On
# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /lumen/public/$1 [L,R=301]
# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
