Some HTTP responses do not contain any body. For instance, responses with status codes 1xx, 204, or 304 must not include body. Portal Access adds 'Transfer-Encoding: chunked' header and may add chunked body with empty payload to such responses.
Most browsers ignore invalid 'Transfer-Encoding' header and/or body for responses which must not include body at all. And yet, some traffic validators may refuse to pass invalid responses.
HTTP response without body processed by Portal Access
Use an iRule to remove 'Transfer-Encoding' header and/or body from HTTP responses with status codes 1xx, 204, and 304.
Now Portal Access does not add invalid 'Transfer-Encoding' header and/or body to responses which have no body.
