I have a script that tests a compiled list of HTTP proxies to see if they can connect to a specified website. If they connect, and the correct page results are returned, they are added to a list of working proxies; however, even if I test about 30,000 proxies at a time....none of them come back working.
Yet, when I check a random selection of them in a proxy checker, quite a large portion of them come back working.
Even when I specify the proxy type to HTTP, cURL never manages to make a connection to the webpage and return the webpage contents.
Note: I am setting a user-agent.
As you can see, no results are returned. The contents of the webpage, if any are retrieved, should be posted in the textbox.
