Client does not send POST body to httpd proxy without 100-continue response
Issue
- Our client sends a POST request with an
Expect: 100-continueheader to an Apache httpd server proxying to our application backend via mod_proxy_http. The client never receives a100-continueresponse so the client never sends the request body until the request eventually times out on httpd.
Environment
- JBoss Core Services (JBCS)
- Apache httpd
- mod_proxy_http
- Apache httpd
- JBoss Enterprise Application Platform (EAP)
