I don't know that the various browser makers document this. I do know that towards the time of IE4 and Netscape Navigator that some browsers topped out at 128 characters. Towards 2000 or so URLs of up to 256 characters were fine across common browsers. These days the limits are likely higher. Depends on your audience's choices in browsers, and what those browsers might describe of their capabilities. One wrinkle is that very long URLs are sometimes used with hidden characters to do secret things... I've no discrete URL to pass for further investigation, but very long URLs might eventually end up as being too fragile for security and privacy protection. I don't know your application, but might it be possible to store all the individual parameters for a given view within a serverside database, and reference each combination by a shorter identifying index...? http://www.MyMapApp.com/?id=i87sT (eg) jd -- John Dowdell .
