Severity: 4-Minor


LTM Rewrite Profile in URI translation mode allows modification of HTML and/or CSS responses. Any other types of response should be sent untouched to client. But if original response is chunked, client may receive unchunked data.


If client application expects chinked response, it may not work correctly.


- Virtual Server with Rewrite profile in URI translation mode - Binary data or plain text on backend server - Chunked response from backend server


Use iRule to enable response re-chunking: when HTTP_RESPONSE { if [HTTP::header exists "Transfer-encoding"] { HTTP::payload rechunk } }
