Question

I was experimenting with mod-rewrite. I thought what I wanted was simple but I don’t get the requested file’s URI via REQUEST_URI. Rather the delived name is passed on.

The manual says:

THE_REQUEST

The full HTTP request
line sent by the browser to the server
(e.g., “GET /index.html HTTP/1.1”).
This does not include any additional
headers sent by the browser. This
value has not been unescaped
(decoded), unlike most other variables
below.

REQUEST_URI

The resource requested
in the HTTP request line. (In the
example above, this would be
“/index.html”.)

However the two give different file names in my tests. I have a bootstrap.php through which I wanted to send all requests. This is the test file:

<?php
echo $_GET['requestedURI'];
?>

on the .htaccess file I have:

### REWRITE RULES ###
RewriteEngine on
RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .+ bootstrap.php?requestedURI=%{REQUEST_URI} [L]

Requesting http://localhost/test.htm puts out: /bootstrap.php

if I put THE_REQUEST instead of REQUEST_URI in the .htaccess I get GET /test.htm HTTP/1.1

So why not settle for THE_REQUEST? Well, as soon as a query string exists things break. If I request: http://localhost/test.htm?x=1&y=2 I get GET /test.htm?x=1 the first ampersand breaks things. I think it should be possible to replace all ampersands in the querystring with %26 so that it would work but I did not manage so far…

So can anyone tell why REQUEST_URI fails and how to fix it or how to rewrite the ampersands to %26 in the query string?

Thanks.

EDIT: The above report applies to xampp 1.7.3 on Win 7. I tried it on a production Linux system in the meantime and there REQUEST_URI returns what it should.

You don’t need to explicitly pass the requested URI path and query as you can access it in PHP via $_SERVER['REQUEST_URI']. Thus this should suffice:

RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .+ bootstrap.php
