[users@httpd] Problem with reverse proxy and file upload
Hi all,
I am using apache 2.2.15 as a reverse proxy server in
front of tomcat app server.
https is enabled between the client and
apache reverse proxy server. Between apache and tomcat plain data
flows.
The application needs a file of less than 500
bytes to be uploaded by user. This works fine
without reverse proxy
but fails always when used with reverse proxy.
The other pages
served by reverse proxy server are fine.
When trying to upload
the file wireshark shows the packet as "continuation or non-http
data" and the application gets stuck there.
My
configuration is as follows:
ProxyRequests Off
KeepAliveTimeout 500
ProxyPass / ajp://BACKEND-SERVER:8009/
ProxyPassReverse / ajp://BACKEND-SERVER:8009/
ProxyPassReverseCookiePath / /
Can anyone tell what may
be the problem???
Snigdha
P.S.: Browser used
is Internet explorer

Who knows. Or a proxy in-between. Have you looked at the request at
various points before it hits the webserver?

Why don't you check the apache and tomcat log
files when trying to upload and see if any useful messages?
