Lighttpd configuration, . (dots) in my query string cause 404

I have an address on my site like so:

http://www.ex开发者_JAVA技巧ample.com/lookup?q=http%3A%2F%2Fgigaom.com%2F2010%2F10%2F10%2Fangry-birds-for-windows7-phone-dont-count-on-it%2F

In this example, the dot in the 'gigaom.com' part of the query string is screwing with lighttpd and my rewrite rules. I get a 404 with the dot in, no 404 if I take the dot out. My rewrite rules are below. In case it makes a difference, I'm using symfony 1.4.

If anyone could shed some light on this problem it would be much appreciated!

url.rewrite-once = (
    "^/(.*\..+)$" => "$0",
    "^/(.*)\.(.*)"    => "/index.php",
    "^/([^.]+)$"      => "/index.php/$1",
    "^/$"             => "/index.php"
  )

For anyone having trouble with lighttpd and symfony (I know you're out there, cause there are plenty of unresolved threads on the issue) I ended up solving and answering it below.

OK so after much debugging with the help of:

debug.log-request-handling = "enable"

^^ This is a lifesaver for when you're trying to debug rewrite rules in lighttpd! (it logged everything for me to /var/log/lighttpd/error.log)

I've figured it out. For all those people having trouble getting symfony to work with lighttpd (including the dot problem!) here's a working set of rules:

url.rewrite-once = (
    "^/(js|images|uploads|css|sf)/(.*)" => "$0", # we want to load these assets as is, without index.php
    "^/[a-zA-Z_-]+\.(html|txt|ico)$" => "$0", # for any static .html files you might be calling in your web root, we don't want to put the index.php controller in front of them
    "^/sf[A-z]+Plugin.*" => "$0", # don't want to mess with plugin routes
    "^/([a-z_]+)\.php(.*)\.(.*)$" => "/$1.php$2.$3", # same concept as rules below, except for other applications/environments (backend.php, backend_dev.php, etc)
    "^/([a-z_]+)\.php([^.]*)$" => "/$1.php$2", # see comment right above this one
    "^/(.*)\.(.*)$"    => "/index.php/$1.$2", # handle query strings and the dot problem!
    "^/([^.]+)$"      => "/index.php/$1", # general requests
    "^/$"             => "/index.php" # the home page
  )

If anyone has more trouble, post here. Thanks!

I am using PHP, MySQL, and .htaccess file for rewriting rules. Just sharing so others can also benefit.

My previous rule:

RewriteRule ^([^/\.]+)/([^/\.]+).html$ detail.php?name=$1&id=$2 [L]

It was working with this result: http://www.sitecliff.com/Yahoo-UK/4.html

I wanted the website name instead of the title in the url. After surfing the net, I figured out that the dot is causing the problem as you mentioned above.

"^/(.*)\.(.*)$"    => "/index.php/$1.$2", # handle query strings and the dot problem!

So I changed the rule to:

RewriteRule ^([^/]+)$ detail.php?url=$1 [L]

After this, I got my desired result: http://www.sitecliff.com/yahoo.com
