I hope I can explain this clearly enough, but if not let me know and I'll try to clarify.
I'm currently developing a site using ColdFusion and have a mod_rewrite rule in place to make it look like the site is using PHP. Any requests for index.php get processed by index.cfm (the rule maps *.php to *.cfm).
This works great - so far, so good. The problem is that I want to return a 404 status code if index.cfm (or any ColdFusion page) is requested directly.
If I try to block access to *.cfm files using mod_rewrite it also returns a 404 for requests to *.php.
I figure I might have to change my Apache config rather than use .htaccess
You can use the S flag to skip the 404 rule, like this:
RewriteEngine on
# Do not separate these two rules so long as the first has S=1
RewriteRule (.*)\.php$ $1.cfm [S=1]
RewriteRule \.cfm$ - [R=404]
If you are also using the Alias option then you should also add the PT flag. See the mod_rewrite documentation for details.
Post the rules you already have as a starting point so people don't have to recreate it to help you.
I would suggest testing [L] on the rule that maps .php to .cfm files as the first thing to try.
You have to use two distinct groups of rewrite rules, one for .php, the other for .chm and make them mutually exclusives with RewriteCond %{REQUEST_FILENAME}. And make use of the flag [L] as suggested by jj33.
You can keep your rules in .htaccess.

Here my problem, the site I'm working on has many 404 pages, but they used to be the same pages with a different path
/mens/designers/mens/wales-bonner
/mens/designers/casual-shirts/wales-bonner
/mens/designers/coats-and-jackets/wales-bonner
etc.
THe client wants the redirect to go to the category, so
/mens/designers/mens/
/mens/designers/casual-shirts/
/mens/designers/coats-and-jackets/
I'm pretty sure, there must be a way to have regex rule to cover them all, but I can't seem to find how
Something like
RewriteRule ^/mens/designers/(.*)/wales-bonner /mens/designers/(.*)
but it doesn't work, I don't know how to group the middle part of the URL
Can anyone help ?
I see several potential problems with your rewrite rule:
You have a capturing group in the output URL rather than using $1 to use the result of the capturing group from the input URL.
^/ won't work in .htaccess, only in Apache .conf files. I' would use ^/? instead which will work in either context. That makes the starting slash optional.
You don't include an [R] flag on the rule to make it a redirect.
You don't include an [L] flag on the rule to prevent any following rules from interfering with it.
You can also add "mens/designers" to the capturing group so that you don't have to repeat it in the output. I would suggest:
RewriteRule ^/?(mens/designers/.*)/wales-bonner /$1 [R=301,L]
I am trying to do a 301 redirect with lightspeed webserver htaccess with no luck.
I need to do a url to url redirect without any related parameters.
for example:
from: http://www.example.com/?cat=123
to: http://www.example.com/some_url
I have tried:
RewriteRule http://www.example.com/?cat=123 http://www.example.com/some_url/ [R=301,L,NC]
Any help will be appreciated.
Thanks for adding your code to your question. Once more we see how important that is:
your issue is that a RewriteRule does not operate on URLs, but on paths. So you need something like that instead:
RewriteEngine on
RewriteRule ^/?$ /some_url/ [R=301,L,NC,QSD]
From your question it is not clear if you want to ignore any GET parameters or if you only want to redirect if certain parameters are set. So here is a variant that will only get applied if some parameter is actually set in the request:
RewriteEngine on
RewriteCond %{QUERY_STRING} (?:^|&)cat=123(?:&|$)
RewriteRule ^/?$ /some_url/ [R=301,L,NC,QSD]
Another thing that does not really get clear is if you want all URLs below http://www.example.com/ (so below the path /) to be rewritten, or only that exact URL. If you want to keep any potential further path component of a request and still rewrite (for example http://www.example.com/foo => http://www.example.com/some_url/foo), then you need to add a capture in your regular expression and reuse the captured path components:
RewriteEngine on
RewriteRule ^/?(.*)$ /some_url/$1 [R=301,L,NC,QSD]
For either of this to work you need to have the interpretation of .htaccess style files enabled by means of the AllowOverride command. See the official documentation of the rewriting module for details. And you have to take care that that -htaccess style file is actually readable by the http server process and that it is located right inside the http hosts DOCUMENT_ROOT folder in the local file system.
And a general hint: you should always prefer to place such rules inside the http servers host configuration instead of using .htaccess style files. Those files are notoriously error prone, hard to debug and they really slow down the server. They are only provided as a last option for situations where you do not have control over the host configuration (read: really cheap hosting service providers) or if you have an application that relies on writing its own rewrite rules (which is an obvious security nightmare).
I'm trying to create a rewrite rule for my .htaccess file. I want to include a single dollar sign within it. It is supposed to be something like this:
RewriteCond %{HTTP_HOST} ^.*$
RewriteRule ^\$$ "http\:\/\/domain\.com\/something" [R=301,L]
The problem is that it doesn't work with a single dollar sign, so if I go to domain.com/$ I get a 404. It works only with another letter, for example ^\$a$ - in such case domain.com/$a would redirect to domain.com/something.
The workaround is to create a new folder, rename it to $ and put the .htaccess file there, but I would rather avoid creating multiple folders with no content for such purposes. I couldn't find any reference on the Internet (the official Apache documentation for mod_rewrite was not very helpful). I tried using multiple slashes in different combinations but everything failed. Am I missing something or is it just impossible to make it work this way?
For me it works exactly as expected in htaccess with RewriteRule ^\$$ and requesting "$". Have you looked at the rewritelog / loglevel rewrite:trace8 yet?
How do I rewrite
www.sitename.com/thing/thing.php?otherthing=something-like-this
to
www.sitename.com/something-like-this?
please help me with this as I can't seem to succeed. My host uses apache 2.2. Many thanks for your help!
Update
No I don't need that trailing ? However, I used the Rewrite rule you offered me and it still ain't working. I also added a RewriteEngine On before the rules.
I have Linux hosting, .htaccess and the code is obviously semantically correct, cause otherwise I would get the all so popular 500 internal server error. I placed the .htaccess file in the folder thing and in the root of the site, but it still won't work.
There should be an option to display it in directory format instead of the PHP ? format. If not, you could use the .htaccess mod_rewrite rule to make that display in the /folder/ way.
The way I do it is that I just upload my files and each page name is index.html and then I create folders, and put each index.html in the folder. Like this:
/guidelines/
In that folder is index.html, so instead of it being /guidelines.html it's /guidelines/
Looks better without .html
You need to use mod_rewrite:
RewriteCond %{QUERY_STRING} ^otherthing=(.*)$
RewriteRule ^thing/thing.php$ /%1? [L]
No idea if you meant to have that trailing ? at the end of the rewrite, I don't think that's possible. Note that the ? at the end of the RewriteRule is to get rid of the query string, otherwise, the rewritten URL will still have the ?otherthing=something-like-this at the end.
I am attempting to redirect & rewrite some dynamic PHP URL's to pretty and SEO friendly URLs. I have manged to do this successfully through .htaccess with the following code:
RewriteCond %{QUERY_STRING} ^somevar=green&nodescription=([a-zA-Z0-9_-]*)$
RewriteRule (.*) /green\/%1\/? [L,R=301]
RewriteRule ^green/([^/]*)/$ /script.php?somevar=green&nodescription=$1&rewrite=on [L]
This creates a somewhat pretty URL as follows:
http://www.mysite.com/green/aA43-/
As I say, this works absolutley fine. Apart from one thing. The parameter nodescription contains a non-descriptive random set of letters, numbers and other characters.
I would like to rewrite the nodescription parameter to a more descriptive one. I understand that I can do this with a rewritemap through Apache. However, I have no experience at doing soemthing like this, and I'm not entirely sure where to start.
Normally I would simply alter script.php so that it contains more descriptive parameters, but this time I have no control over the script; I am pulling it from another site using cURL.
Can anybody give me an example of how to pull this off?
Thanks!

Well, to answer my own question, to pull this off you need access httpd.conf file on your apache server. My shared hosting company didn't allow access to this file (I doubt any would allow you access).
So I bit the bullet and purchased a VPS. I will post the steps I took here in order to set the rewritemap up in the hope that it will help a lost soul :) Ok, here goes...
My VPS has WHM installed, so in WHM I went to:
Server Configuration >> Apache Configuration >> Include Editor
Pre Virtual Host Include >> All Versions
This feature takes any text you put in and includes it in your httpd.conf file without worrying that it will be overwritten at a later stage. If you don't have WHM on your server then you can add the text directly to your httpd.conf file; make sure it is outside and before any virtual hosts.
OK, so I included the following map declaration and rewrite rule:
#Map to redirect (swaps key and value)
RewriteMap rwmap txt:/home/*/public_html/rdmap.txt
<Directory /home/*/public_html/test>
Options All -Indexes
RewriteEngine on
RewriteRule ^url/([^/]*)/$ /script.php?foo=${rwmap:$1|$1}&rewrite=on [L]
</Directory>
The actual map is a simple text file containing key/value pairs - you need to place this file in the directory declared in RewriteMap rwmap txt:/home/*/public_html/rdmap.txt.
And there you go. Apache now rewrites my URLs for me and I now have some nice and pretty SEO optimized links thanks to my rewrite map! Hoorah!
RewriteEngine on
RewriteRule ^green/([^/]*)/(.*)$ /script.php?somevar=green&nodescription=$1&rewrite=on [L]
This rewrite will allow you to pass "arbitrary text" that has nothing to do with the rewrite. For example:
http://www.mysite.com/green/aA43-/some-seo-boosting-title
Will still reroute correctly to script.php; the latter part will simply be ignored by the rewrite.
