Severity: 3-Major


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


Remove the compression profile, or modify the compression profile to ensure the response in question is no longer eligible for compression.
