VCL failure is invoked if: - no entries were added to a set - a set was not compiled - .compile() is called in a VCL sub other than vcl_init - a numeric index is out of range (larger than nmembers) - the conditions for UNIQUE or EXACT fail - associated data to be retrieved (string, backend etc) was not added If .match() or .hasprefix() are called with a NULL subject, it is logged using tag Notice, but is not an error (return value is false). This is because it may or may not be intentional to attempt a match against an unset header. The .matched() method now may have a select argument, and works similarly to other methods with the f(INT n, ENUM select) signature, except that it returns false when the select condition fails, but does not invoke VCL failure. This makes it possible to check if UNIQUE or EXACT may be used, and avoid VCL failure if desired.
