Yes, breaking it up would work, but that is not a solution for streams. The regex is dead simple: /Authorization: Basic (.*)\ngrant_type=refresh_token/ "." doe

Yes, breaking it up would work, but that is not a solution for streams. The regex is dead simple: /Authorization: Basic (.*)\ngrant_type=refresh_token/ "." does not match newline, so I'm basically looking two lines that conform to a template. Specific cases can be transformed with some grep/awk magic, but IMO the concept of pattern matching against a stream is interesting regardless.
