Unable to access the application via ADC, when ADC is bypassed; users are able to access the URL.
Issue is seen from the day new backend server was introduced.

You have following option to mitigate this problem:

1: Remove Insert Client IP setting on vServer.

2: Apply rewrite setting to insert X-Forwarded-For header.

3: Upgrade, Issue will be addressed as enhancement in future release.

Problem Cause

During analysis of packet capture, We see in the request packet we send to the backend server, that in the X-forwarded request, ADC is adding a space character at the end of client IP before sending it to the backend server.


We disabled the X-forwarded header, and issue disappeared.

The new server didn't accept the format of X-Forwarded-For header, that ADC sends.
It was found, this format used by ADC is still as per RFC standard.
However due to more stringent format check by backend server, this packet was discarded.
