Code updates

Anyone have a URL for a code patch fixing the gzip file length bug?  I 
would really like to be able to use gzipped HTML and CSS files to reduce 
bandwidth usage.

Also, I want to have the functionality in tux to do some very simple 
client detection for content delivery.  Basically it boils down to an 
array of strings:

"MSIE 6"    "index.xml"
"Nokia"    "index.wml"
"UP"    "index.wml"
"Wapalizer"    "index.wml"
""    "index.html"

So instead of always just serving index.html at a trailing slash if 
available, it would return the content type most appropriate for the 
client based on a simple substring match;  First match wins the prize. 
 It seems to me that this wouldn't introduce a noticeable amount of 
overhead to the server compared to the flexibiity.

I am not familiar with the codebase.  Where would be the best place to 
start?
