The W3C sorta leaves this up to the server. Here's an excerpt from the
HTTP/1.1 spec <ftp://ftp.isi.edu/in-notes/rfc2616.txt>:
----
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.
----
So, the answer is, "it depends."
Try yours with a 100K URI and see if it barfs.

Nope, the clients may impose a size limit.
