It's on NT, running IIS 5. The script has extension .cgi The server is actually not with us. The strange thing is, we have another client using a similar script, same extension, and that one works fine with NS & IE. And this problem apparently only became a problem today. um... how do I send a header? Thanks again Karen ------ yep, try sending a header... what's the extension of the file? what platform/server? sample related issue: http://lists.evolt.org/archive/Week-of-Mon-20010122/149055.html
