Is it possible to make the tests (both TCP and UDP tests) not rely on external
website?

[Dmitry Polukhin, 2011/11/29 20:09:38]

Yeah, unfortunately we didn't find how to make it work with internal test server
for NaCl (it looks like testing HTTP server has problem with requests that comes
during testing - need more investigations). In addition with local server we
won't be able to test SSL handshake. It looks like over tests use
www.google.com/robots.txt too, like GetURL. I propose to add TODO to replace it
with internal server in next CL that should be much smaller.

Okay. Thanks for explaining.
