Symptoms

There is a 502 Proxy Error displayed in the browser, when users try to submit portlet page in Oracle Portal through webcache. Portlet displayes Java EE application implemented using Struts framework.

This error occurs after upgrading Oracle Portal 10g to Oracle Portal 11g. Let me know,

1. The request to the Portal includes a very large POST as can be seen in Data Collection record. The web cache trace dump references a large POST body similar to the one shown below (although you may not see this specific content with "@@POST_BODY_TOO_LARGE" in the trace dump):
