Symptoms

When using the HTTP::redirect iRule, it results in a response header beginning with the following string: HTTP/1.0 302 Found This could be considered non-RFC compliant, since the HTTP version is 1.0, but the status text is correct for HTTP/1.1. For strict RFC compliance -- HTTP/1.0 responses should specify status text 'Moved Temporarily' (RFC 1945 Section 9.3). -- HTTP/1.1 responses should specify 'Found' (RFC 7231 Section 6.4.3).

Impact

Clients should be relying upon the numeric HTTP status code, and not the status text that follows, so in theory, there should be no impact. However, those clients which use the status text for processing decisions must be ready to handle status text that doesn't match the specified HTTP version.

Conditions

When using an iRule similar to the following HTTP::redirect redirect

Workaround

None.

Fix Information

HTTP::redirect status string is consistent for HTTP version.
