Proxy Retry Logic

[Sirsiwal, Umesh]

Thanks Marcus,
In my application, I need to know once the subrequest has finally completed. I already have a module specific context attached with the subrequest. So I can easily use that to keep track of number of callbacks.

Or test to see if you've already run the post_subrequest by creating a
context struct and a flag to say whether you've called the function
before (but personally I prefer the former because then you don't end up
calling the same function loads of times unnecessarily).
