Regular Expression Question

Hey ya'll...I'm trying to use the mod_rewrite function in apache to basically make my web pages case insensitive.  I've made the htaccess, and used this:

RewriteEngine on
# mod_rewrite engine enabled

RewriteRule $1/(.*) [nocase]
# mod_rewrite rule for case insensitivity

However, it doesn't seem to be working, obviously.  I think it's my RewriteRule - does anyone know what the reg ex would be to match our url?  We have several different urls (url1.com, url2.com, url3.com), and people could use cases wrong.  For example, these all would need to go to url1.com/Testdir/Testpage1.php:

url1.com/testdir/testpage1.php
url2.com/TeStDiR/TeStPaGe1.PHp
url2.com/TESTDIR/TESTPAGE1.PHP
url3.com/testdir/TESTpage1.PHP

Any thoughts?

The problem is with changing the case of the URls. Do you really need that?
Generally you can't change the _case_ of the expression with regexps; you would need to use the extended rewriting and have some CGI script to do that;

Otherwise, the regexp for what you posted is quite simple:

url(\d+)\.com/(.*)$           url1.com/$2

I don't think it can be done automatically, you have to tell Apache which URLs must be considered accepted, and redirect to the correct URL.

Something similar may do. (Not tested.)

# Exclude when correct REQUEST_URI and SERVER_NAME
RewriteCond ${REQUEST_URI} !^/Testdir/Testpage1\.php$ [OR]
RewriteCond ${SERVER_NAME} !^url1\.com$
# nocase compare, redirect to correct domain and path
RewriteRule ^testdir/testpage1\.php$ http://url1.com/Testdir/Testpage1.php [NC,R,L]

Good luck.

Btw I assumed that url1.com, url2.com, url3.com are domain names.

Also, for all your rewriting needs, have a look here:

Well, I'm a bit confused...I know that Windows has this functionality, while linux file system doesn't.  I was hoping that either mod_rewrite or mod_speling would do the trick...I just want to not have people get confused over case, like when they forget the to cap the first letter of the folder name.  I would prefer not to do it on a page by page basis, but I'm a bit foggy headed.  If you could "dumb down" what you said a bit, I'd be greatly appreciative...

Now that you mention it, why not use mod_speling, if available?

Well, take that with a grain of salt...I have yet to convince my web host to re-enable that.  In their words, they said they are using mod_rewrite as a better substitute, although not as simple. :-P  Go figure...anywho, so I just do "CheckSpelling on" and I'll have all the bells and whistles?

Yup, should be. That's mod_speling's only option, it's "on" or "off". :)

Good luck convincing your host.
