Opened: Mar 12, 2019

Severity: 3-Major

Symptoms

Reading an object from the BIG-IP system.

Impact

The client will wait for the BIG-IP to deliver the amount of data specified by the Content-Length header, but since the object was compressed, there isn't that much data to deliver.

Conditions

The virtual server has both a web acceleration profile with an active application and the HTTP compression filter on it. When reading a compressible object from the web acceleration small object cache, the HTTP compression filter may compress the data, but not rewrite the Content-Length header.

Workaround

You can use either of the following workarounds: -- Remove the HTTP compression filter from the virtual server. -- Mark objects smaller than 4,000 bytes as no-store.

Fix Information
