The BIG-IP fails to remove chunk headers when compressing a chunked response from a pool member. The chunk headers are compressed and delivered to the client as part of the payload.


Chunk header and terminating 0 length chunk are compressed and delivered to the client as part of the payload, resulting in broken application functionality.


-- Version with the fix for ID902377 -- Rewrite/HTML profile -- Compression profile -- Chunked response from pool member (With "Transfer-Encoding: Chunked" header) -- HTTP response eligible for compression


One of the following: - Change HTTP response-chunking to either 'unchunk' or 'rechunk' in the HTTP profile for the virtual server. - Remove the compression profile. - Modify the compression profile to ensure the response in question is no longer eligible for compression.
