Length of get parameters

Hi all!

Please tell me how long the GET parameter can be. Is there a limit for
each parameter itself, or a limit in the whole?
I thought there would be a maximum of 1024 characters, but it seems to
work with more.

Part of the RFC2616 (@ http://www.ietf.org/rfc/rfc2616.txt) states:

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, to be safe I'd try to limit the whole thing to 255 characters or
less :-)

I have a spam filter working.
To mail me include "urkxvq" (with or without the quotes)
in the subject line, or your mail will be ruthlessly discarded.

I think it's really nice to be able to do code like someVariable = someMethod(new SomeClass("some text")); However, as method signatures are number and types of parameters, you're limited to having one constructor that accepts a single string, for example.
