Subject Re: HTTP Error 302
Date Mon, 24 Nov 2003 07:18:13 GMT
after investigating the Problem, we found that we generate a redirect to
login when
the session is invalid. We have a servlet, that generates Images. If the
client requests the Image servlet directly everything is fine. The session
is valid and the user gets his image. But when the client want's to generate
a PDF with FOP on the same webapplication where the Imigegeneratorservlet
is, we dont't get a valid session. The request to the Imagegenerator is
comming now from the webapplication and not from the client. So there is no
session and we generate a redirect to login. I monitored the datatranfere
with tcpdump on the loopback device and there I saw the HTTP 302.

What is the best way to handle this kind of session problems.

Thanks for answeres
