I assume you mean to ask whether there is a limit on the size of the URL,
and the answer is yes. However, this depends entirely on the Web server
and Web browser involved in a particular transaction. It is not something
that is defined in the specification.
For example, if your Web server can handle URLs up to 2048 characters in
length, and a user's Web browser can only handle URLs up to 256 characters
in length, that particular user will have trouble when you use URLs over
256 characters, while other users may be fine.
As far as recommendations, I can't recall where I read this (I believe it
was on the W3C Web site somewhere), but you can follow these rough
guidelines:
< 256 is very reliably handled by practically every Web agent
<= 1024 is reliably handled by most modern Web agents
> 1024 is not generally recommended
Of course, the total length of the URL is greater than the query string
alone, so you'll have to keep that in mind if you're splitting hairs.
Hope that helps.
