WAF is Removing Headers to Real Server
WAF was not adding HTTP headers when traffic was sent to the real server
WAF was removing HTTP headers. When WAF was turned off, headers were added back in.
|Steps to Reproduce:||
|Cause:||The issue was 'Chunked' data was being sent by the client using HTTP POST. That kind of data along with WAF being turned on caused headers to either be removed or not added in from the LoadMaster to the real server (RS).|
|Resolution:||This will be fixed in an upcoming firmware patch.|
The purpose of the work around is to close the connection before the next request.
