Make a HttpWebRequest GET request using a proxy, the proxy should be loaded from a file whatever.txt the proxy format is 0.0.0.0:00 ( $IP:PORT) the HttpWebRequest should use the proxy to make the connection the whatever.txt file is contain a list of proxies like this $IP:PORT $IP:PORT $IP:PORT each line in the file has a one proxy so basically this steps should the code do:
1. Load one proxy from the whatever.txt file
2. Send Get request to my custom URL
3. if the proxy connection time out is more than 1.5 second then load a new proxy from the next line
4. each proxy should use multi-threading, making 10 connections per request
5. if the list of the proxy list reaches the end then start from line 1 and repeat you can use any proxy list you want for test purposes.
