The BIG-IP device can request gzip-encoded or deflate-encoded content from the origin web server to accelerate responses. When the Enable Assembly Compression OWS check box is selected (enabled), the BIG-IP device sends an Accept-Encoding: gzip,deflate header to the origin web server. The origin web server complies only if it supports the compression mode; otherwise, the origin web server provides uncompressed content.

This functionality occurs independently of selecting (enabling) the Enable Content Compression check box, which sets the compression for the response that the BIG-IP device sends back to the client.
