Server Config: Win2k Tomcat 3.2.1 port 8080 IIS 5.0 port 80 Browsers: Internet Explorer 5.0 (MS VM build 3240) Netscape Communicator 4.74 I have an applet communicating(POST) with servlet. Without IIS, when using URLConnection Explorer will work but Netscape will hang the browser. Using Sockets will work on both Explorer and Netscape. I think using URLConnection with the event thread is the culprit because my polling thread works fine on Netscape. Anyway, when I used IIS I started to get more problems. The normal servlets outputting HTML work fine. But the servlet which receives the POST from the applet has problems trying to get the InputStream. Checking the getContentLength of the request returns -1. It looks like IIS isn't sending the POST data to Tomcat. This was with URLConnection. Using Socket will not even cause the servlet to be called. Any ideas? cheers, Peter --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
