Re: [Grinder-use] Dynamically replacing a parameter in the URL

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Thank you Ravi,
Originally I mentioned I was using 3.1.1, should have said 3.11.  Anyways,
really good info on the site, definitely helpful.
I do not think I was very clear on my initial posting. I have used some of
your info to get at what I need now I have another question(s).

My snipped file has been included here for reference as it is clear I am
not really sure how it all works (see the comments with #************)

I have created a helper method that will extract the SRN parameter on the
apropriate response (the third response).

In request 4, the recorded value of
''HE1YHZvKcjjBo8TMBY5cdfVweOyMRbfYKfE33mJL1bYb'' is what I want to replace
with the value that was extracted with my helper method.

First Question, how can I assign the value I extracted in my method to a
variable that is accessible from the next request?  Is it a member
variable?  If so, where does the definition of that member variable belong
and how do I assign my value to it?

Once I can do this, the next question is how can I replace the recorded
value for the SRN parameter in the headers2, headers3, headers4?
