Release a Sticky Session
If you would like to remove the assigned proxy from your sticky session you can do this by executing a request through your sticky port to the following end point:
curl -x premium.residential.proxyrack.net:10000 -U username http://api.proxyrack.net/release
Then on your next request through the sticky session a new proxy end point will be assigned
You can also programatically do this with your code by visiting the exact same URL.
