Please can someone help me understand the following logs...

Tomcat log did
not show any error message.

Apache error log showed the
following:

Apache access log showed the following:

For file upload I used multipart/form data.  
-----------------------------7dbf174027e, etc are actually boundary for
the multipart form data. 
I can not understand why apache will
mistake the boundary of multipart form data as a method.

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

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???
