The HTTP iRule commands behave differently if they return only a single result. They will return a Tcl string rather than a Tcl list containing a string.
A string is returned rather than a list. This may affect Tcl code that expects the result to be a list, leading to incorrect behavior.
One or more of the following HTTP iRule commands are used, and the conditions exist such that a single result is returned: HTTP::cookie names HTTP::cookie attribute names HTTP::header names HTTP::header values
If the result is not a list, this can be detected in a Tcl script, and the result handled as a special case.
HTTP iRule commands that return a Tcl list will do so in all cases.
