will long urls slow down server?

[juschillinnow]

I was doing a little testing with a script and I was using

$_SERVER[REQUEST_URI]&this=that;

and I was using that for every link. So obviously everytime someone clicks on a link, the url gets longer.

If someone clicks on a thousand links, what are the dangers and will it slow the server and requests?

How does this work exactly?

As you are aware, the url is sent using HTTP headers not the body (thats the post).

The maximum size a url can be is something like 1000 and a bit characters. This should really be ample.

In terms of speed, reaching the maximum length shouldn't really be a problem for the server to deal with, however if you are setting a load of variables using all these characters (leading to alot of variables) the processing script could see a slowdown and be where the process is most likely held up.

Hope this answers some of your questions.
