F5 APM and "Keep Accept Encoding"
Hi there,
Have an app that works fine directly through LTM on the LAN but not via APM Portal Access (11.4.1)
After lots of tracing/HTTPWatch and TCPDUMPs the vendor states that the F5 platform is stripping the Accept-Encoding header and that we need to disable compression or enable "Keep Accept Encoding".
On the LTM VIP for the App (direct) compression is not enabled, on the LTM VIP for the APM Portal Acccess it is.
Disabling compression on the LTM VIP associated with the APM Portal doesn't solve the issue. Creating a custom HTTPcompression with "Keep Accept Encoding" enabled and applying this to the LTM VIP associated with the APM Portal doesn't solve the issue.
Can anyone think there a reason why when APM is configured that the F5 platform is stripping the Accept-Encoding header even though compression is disabled at the LTM VIP level?
Also ideally I don't want to disable compression on the entire APM Portal as it might impact the other apps accessed.
Have raised a case but interested in any thoughts!
