Topic awaiting preservation: URL re-writing. (Page 1 of 1)

So I am starting work on a content management system that uses Perl to take a generic HTML file and make multiple translations of the file for use in various browsers (text-only, v4- browsers, and CSS browsers). So a single page will have multiple versions mirrored in a number of parallel web root directories.

When a URL is requested, a PHP script will parse the USER-AGENT string and determine which of these directories to grab the page from, then will insert the page into a template, maybe load even more specific style information, and then output the page to the browser.

The thing about this is, it would require each page on the site to essentially be the same script. So what would be the best way to set up Apache so that URLs like:
http://www.coffman.umn.edu/url/
& http://www.coffman.umn.edu/url/?var=bleh

get translated to:
http://www.coffman.umn.edu/?path=url
& http://www.coffman.umn.edu/?path=url&var=bleh

jiblet: Put something like this in your .htaccess file:

RewriteEngine on
RewriteRule /([^/]+)/([^/]+)/ /?path=$1&var=$2

which would make:

/something/otherthing/ -----> /?path=something&var=otherthing

Hm, simple enough, although that is not exactly what I mean. Probably more like this:

/([^\?]+)\?(.*) /?path=$1&$2

Since it's supposed to preserve a URL of any length, and concatenate passed variables so they pass through the rewrite.

I have two questions though:

Does this affect what gets written to the log? Is the original URL request logged or the rewritten URL?

What about in the browser? Does the browser actually get forwarded to this new URL or does it appear to be coming from the original URL?

jiblet: Cool as long as you got it to work. To answer your questions:

1. I'm not sure I've only been playing with this properly for a week or so,

2. You get the URL that is typed in not the one that is being masked.

Have a look at the following for more mod_rewite stuff:

To redirect web browser to the new location you need to use [R] flag (read Apache documentation for more information)...

RewriteRule Pattern Substitution [R]

Ah, thanks very much guys. Yes, the default URL behavior is what i want here. Reading the documentation was most enlightening in the description of processing, especially how .htaccess processing is slow compared to adding the directives directly the httpd.conf file. Fortunately I have a dedicated Linux box all to myself and a master admin providing free support

Makes me want to learn more gory details about Apache server function

Alright, I've basically got this working the way I want (on a per-directory basis, although it will be inserted to the Virtual Host config as soon as I get it completely figured out).

The problem is this:

It would appear that Apache strips variables out of the URL before re-writing. The problem is, after rewriting the variables seem to be gone. Is there something I should know about propagating GET variables through rewrites? or is my problem somewhere else?

Add %{QUERY_STRING} to the substitution pattern, where you want it to appear...
