Question

I have internet connection via http proxy, and some of my web applications at localhost need to access internet. Where can i set up proxy settings for them?

Answer 1

All I needed was to set system.net in web.config

<system.net>
    <defaultProxy>
      <proxy
        proxyaddress="http://10.0.2.231:42"
        bypassonlocal="true"
      />
    </defaultProxy>
</system.net>

See: Element (Network Settings).
