Hi

I have a CGI program that takes a set of parameters in, builds a graph, saves 
it to a JPEG file then reads the jpeg file back writing it to the standard 
output port.

This has worked fine on all versions of IIS it has been run on but when I run 
it on Tomcat v4.1 on Windows NT workstation 4 it corrupts the data stream 
being sent to the web client. The JPG files generated on the web server can be 
opened with no problem and looks fine, however the image presented on the web 
client is garbled. I have saved the image at the web client and file compared 
it in binary mode to the jpeg on the server and it appears that ascii 
character 63  or ? is sporadically overwriting bytes in the jpeg data stream. 
Enough to corrupt the whole image. Note the file size of the server JPG and 
the client saved JPG are identical.

Have you any ideas what could be causing this?

Many thanks in advance
Neil Fuller
