I've got a situation where I had a coder create a wordpress plugin for me but the proxy checking subroutine is sort of suspect, in my view. I need to pass along what others think is good code to throw an array of 1-x number of proxies to test to see if they're still good at the time of testing for google scraping actions. Willing to even pay to have a the old check routine substituted for one that actually work. But I sort of figured a php routine already exists out in the nether..no? Basically I'd think it'd check for 201, 401, and then report back for good/bad.
