This is related to the so-called "content negotiation":

http://www.w3.org/Protocols/rfc2616/rfc2616-sec12.html

For example, a browser could send a language preference, e.g.:

Accept-Language: en-us,en;q=0.5,fr;q=0.1

In other words, give the content in American English, English, or  
French, in that order of preference.

The "quality" value (e.g. q=0.5) provides a mean to sort the  
preferences.

Another common example would be encoding:

Accept-Encoding: gzip,deflate

This tell the server that the content can be compressed when sending a  
response, and that gzip would be preferred over deflate.

In any case, will hack something with the string library :D
