> I've been receiving occasional errors from the Mashery Proxy in front of the GoGrid API.
I have modified the GoGrid driver to do the following:
> 1. Use POSTs in place of GETs for API calls with the potential to provision, destroy
or reboot servers. These aren't actually used in the fix I eventually settled on, but should
probably be used in any case.
> 2. When checking for the success of a request, check for headers indicating a proxy error
and raise an exception specific to this error.
> 3. Implement a counter to retry requests up to 20 times, once every 10 seconds, when
these errors occur. I haven't spent too much time tuning this, but with 10 retries I was still
getting occasional failures.
> I'll be attaching the patch momentarily, or these changes (among others) have been applied
to my github fork at: http://github.com/russellhaering/libcloud
