Sounds like you might want my "watching long processes through CGI" column. -- Randal L. Schwartz, Perl hacker Be sure to read my standard disclaimer if this is a reply.	[reply]

Without more information about your environment I can only offer generic help - Option 1 - increase the timeout setting on you web server Option 2 - speed up your server side script My experience has been that it almost always pays to take the second option, since you often have to do that anyway. As a starting idea, you could look at caching results on the server.	[reply]

If all your processing is done in a loop, you can just print a single space character to the webpage. It won't display anything but the browser will be happy as its still receiving data. CC	[reply]

I often find that running the main processing in a seperate script in the background, then at the end of this 2nd script, e-mailing the results back to the user, is more effective. Of course this is not always applicable & the above answers are also good options. If the Problem is speed , perhaps you should post your code & we may be able to offer performance suggestions. I should really do something about this apathy ... but i just cant be bothered	[reply]

If the script takes a few minutes to proceed, I think it is not the server who is causing your problem, but the user. To please the server, or the clients box, you could flush the content. Use $\| for that, and it forces a flush after each print. But which user will wait a couple of minutes for a website to load? I wouldn't... snadra	[reply]

Hopefully this page isn't publicly accessible? Else I can DOS your server from bash command line: `while true; do echo -e "GET /yourcgi.cgi HTTP/1.0\n" > /dev/tcp/yourhost.com/80 done` [download] +++++++++ In theory, theory describes reality, but in reality it doesn't.	[reply] [d/l]
