Check if response contains text

[flamery]

I would like to test a specific url and check it returns a string of text. The site I am checking actually returns a response code of 400 and some text in Json string. Currently this script reports it as failure for all proxies.

The reason for such a request is if the site I am scraping is gaming or xxx for example a lot of proxies will open Google.con but refuse to open these sites due to url filtering therefore to have a useful proxy list we need to make the proxy.check more granular.

Thanks if you can help
