problem with a page not loading

[rupertshih]

Hi

I got a problem with a page not loading
basically,
1. get a proxy from a file
2. go to a page
at this stage, the page sometimes load and sometimes not due to proxies die out.
what should i do if I want to reload a proxy and then the page again?

by the way, I have a list of proxies which mix public and private and private proxies usually do not work but public proxies work better than private proxies. Why is that?

and question is that when loading a page with zennoposter, it loads slow. Why is that?

Thanks
