seems to me that "pdf:" shouldn't be part of the resource id.

[hshi, 2012/04/20 22:04:51]

I also assumed "pdf:" is not part of resource id initially, but it looks like
our TOT cache codebase indeed treats it as part of resource id string. See
gdata_file_system_unittest.cc: RemoveFromDirtyCache for example.

You are right. would be nice to mention it in the function comment in the header
file.
