Change part of an HTTP GET request

[andradrr]

Hi JJoe!

First of all thank you very much for your time helping me! It worked like a charm!

Second, sorry for the real link I posted that redirects to an adult site. I should imagine that it was not a good thing to do.

Third, can you explain me two things?

1- What does the !: header command do? I could not find it in the docs.
2 - Why the following do not work? In which case I will use the replace box?

[HTTP headers]
In = FALSE
Out = FALSE
Key = "URL: Change position"
URL = "http://prxbr.com/members/materials/stream2.php?file=0017m/medium/0001&position=0"
Replace = "http://prxbr.com/members/materials/stream2.php?file=0017m/medium/0001&position=12345"

Again, thanks a lot for your help and free time.

Cheers,

Rodrigo.
