Strange problem when installing IIS and WebSphere on different PCs with Windows 2000

[Ian Wang]

Dear all,
I met a very strange problem. Maybe somebody can help me.
I write a program to upload file to server. It works when IIS and WebSphere 4.0 run in the same PC.
But it fails when the file size is larger than about 50k and IIS and WebSphere 4.0 run in the different PCs.
I found the first 50k content is right. But the left portion are null(0).
It seems that only the first 50k will be tranfered correctly from IIS plugin to WebSphere if I install these two in different PCs.
Did anybody meet this problem?

I don't know what the deal is with IIS- but possibly you can implement it(uploads) using a different method. Check out this site- I'm using this upload servlet in production, and you can specify file size on it. I used the MultipartRequest servlet provided at orielly. Its great. http://www.servlets.com/cos/index.html

We are having the same issue with uploads using IIS and WAS on different machines. Files upto 50K seem to be fine but anything over causes errors. Anyone have ideas as to what is happening?

What version of WebSphere are you running? There were problems with this in 4.0 and 4.01, but it should have been fixed in 4.02.

We are running 4.04, IIS 5.0 SP3 on Win2k. Here is a little more detail:
IIS 5.0/Win2k with plugin outside the DMZ firewall <==> WAS 4.04 on iSeries in the DMZ, behind the firewall.
IIS handles all of the static traffic (serving up html, images, PDFs etc) and WAS handles all of the dynamic stuff.

On iSeries we are running 0S/400 V5.1.
