The latest http spec is rfc2616, available from:
<URL:http://www.rfc-editor.org/>
Quoting from it:
"3.2.1 General Syntax
The HTTP protocol does not place any a priori limit on the length of
a URI. Servers MUST be able to handle the URI of any resource they
serve, and SHOULD be able to handle URIs of unbounded length if they
provide GET-based forms that could generate such URIs. A server
SHOULD return 414 (Request-URI Too Long) status if a URI is longer
than the server can handle (see section 10.4.15).
Note: Servers ought to be cautious about depending on URI lengths
above 255 bytes, because some older client or proxy
implementations might not properly support these lengths."
You can also find some discussion in the archives of the servlet
interest list. Although I don't remember anybody listing
particular browser/proxy limits, it might be worth a look.
