Greetings. Over the past few weeks I've been trying to isolate why some
dynamically generated PNG graphics are not visible to the client. The
application is deplayed in a multi-tiered implementation.
IIS 5.0 webservers running the isapi jk2 ajp13 connectors to tomcat
application servers running version 5.0.19. In addition cgi support is
enabled and this works fine when not using the ajp13 connectors and going
straight to the tomcat application server.

Now, I have been successfully sending other types of files, and images,
including png back across the pipe -- but for some reason, this doesn't
want to work. Is there anything else I can enable or check to help
resolve this issue?
Is this something that could be resolved by implementing the newest isapi
jk2 dll?
Thanks in advance.
