Hi - I have a function that uploads a .mpp file via http. Running on one test box, it functions perfectly. Running on another, MS Project cannot open the file. I've viewed the HTTP logs and the only difference I can see between the successful and the unsuccessful POST is that the successful one contains the Content-Length parameter. Why would the same exact code post the Content-Length on one box and not on another? Here are the POST requests. This one works:

POST http://192.168.1.20:58080/pce8/admin
Referer: http://192.168.1.20:58080/pce8/admin

Content-Disposition: form-data; name="op"

The functioning box has Windows 2000 Server, the failing box runs Windows 2003 Server. They run identical installations of Perl, have the same libraries, etc. Does anyone know of this problem and have any solutions? My preference is to host my program on the 2003 Server box, but I can't with this issue in the way. Many thanks - PlugNPlay
