Description Shekar 2018-06-26 16:36:08 UTC
When a user uploads a file using Internet explorer to our application, the apache shows an error code 400 in the access log and below error in error log.

[Thu Jun 21 15:47:03.145668 2018] [proxy_ajp:error] [pid 1759:tid 140304137443072] (70008)Partial results are valid but processing is incomplete: [client XX.XX.XX.XX:54472] AH02822: dialog with client XX.XX.XX.XX:54472 failed, referer:

we are using proxy ajp module to pass requests to the tomcat server. 

when this issue occured, we observed that the actual request went all the way to tomcat and tomcat successfully processed request. But in the middle of processing itself the apache returned an error 400 with above error.

The browser shows request status as "Aborted" when we ran the IE developer tools->network trace.
