Hi i want some help with Hrefer Proxy setting.In Hrefer there is a folder Proxyc that has a a file called list there are many urls from botmaster.When i add a url in Hrefer proxy setting.It show 0 proxies.Do i need to add proxies in xproxy.txt file located in Hrefer folder or it will extract proxies automatically and store them in xproxy.txt file?
Kindly Help

You Not Need to add proxies in xproxy.txt
you can just add botmaster proxies url & than update proxies

But when i put that url in hrefer and run start parasing google clasis .... It shows that proxy is disabled.Why is this? it doesn't show any proxy next to threads?and when i add proxies in xproxy.txt . then i can see proxies?Could you please explain this.
Thanks
