The [^] don't do what you think they do.

In a regex, [abc] means, match a single character that is either a, b,
or c. [^abc] means match a single character that is not a, not b and
not c. It does *not* mean to match a three-letter string that is not
abc, or anything like that.

I think you are trying to write a negative look-behind, something like
(?<!http//:) but it's hard to be sure without seeing your code.

Did you try Denis' suggestion of a single regex to match both patterns?
