Re: numberOfRetries Modification

I agree with the exceptions, but so far i could not really come up with a good
layer that is not just duplicating the information in the underlying exception.

So all we have is the responseText property so far to make it a bit easier to
get at the errorHTML from the server.

Do you have some suggestions on what type of exception subclasses you like to see,
and what they should expose?

Thanks Frank for the tip,

I changed it through the service's factory after creating the service.
This way is definately cleaner than editing the source code for the
authrequestfactory. However I cast the factory into
GDataAuthRequestFactory instead of a GAuthRequestFactory.

I noticed this happens the most while debugging, maybe the keep-alive
timeouts while looking at some values/code, also when there are
subsequent calls (in a loop for instance) with other time-consuming
statements seperating them. Also it definately happens when a torrent
is eating up most of my bandwidth :0), but no proxies.

I wanted to point out that the way the cs library generates exceptions
is very uninformative and not really useful; I get the same exception
when I query a wrong or malformed URL, and also when there are
connectivity problems and that I have to look into the inner exception
in my code. I hope we have several exception classes in the next
releases.

Thank you for the help, I would love to help with the APIs if possible,
