Visual Studio doesn't cache Microsoft Symbol Server cache misses?

Question

I'm using the Microsoft Symbol Server with Visual Studio 2008 and it's working pretty well. Unfortunately, when the public symbol server doesn't contain the symbols, it takes a while to timeout, and Visual Studio attempts to reload the same missing symbols every time that I start my project for debugging.

Is there any way that I can get (or trick) Visual Studio into remembering the "misses" and not to bother again for a while?

Answer 1

See this post
But it seems you can also control symbols loading with symsrv.ini
(I guess the ini file should go under ...\Microsoft Visual Studio 9.0\Common7\IDE folder)

Update:
Just found this link. Using the registry is better than the ini file approuch.

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Symbol Server\Exclusions]
"notepad.pdb"=""
"ora*.*"=""
