When URL contains - same matching functionality as Url patterns?

[MatzFan]

I cannot get SimpleModifyHeaders to recognize a 'When URL contains' pattern. What is the logic here, the same pattern matching as used by the 'Url pattern' matcher (i.e. including path wildcards) simple URL string contains sub-string, or something else?

Thanks in advance, great extension BTW.

I am also facing the same issue. 'When URL contains' seems to be ignored. I presume 'Url patterns' should be disabled or should automatically include all URLs when 'When URL contains' is present, to avoid confusion.
