Autoediting server response by the rules with Fiddler.

Question

I have flash application. It repeats response, which returns in the answer servertime. For expamle it could be "("1234567");".

I want to automatically do the following, with Fiddler:

1) Recieve servertime in variable from 1st response (onwards "T"). 2) On 2nd query, I need to replace real time with number T+1 . 3) In the following query, it should already be T+2, etc.

How can I implement this?
