[Bug 11172] New: no web cache

http://bugs.winehq.org/show_bug.cgi?id=11172

Summary: no web cache
           Product: Wine
           Version: 0.9.53.
          Platform: PC
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wininet
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

As far as I can tell the wine wininet does not implement cache. This in itself
would not be that troublesome but there is unimplemented function
InternetSetFilePointer that appears to rely on cache from the msdev
description, and I have no idea how to implement it without one.

It appears that a game updater relies on this function to cache a file
completely so that it can be read easily. It calls it with zero offset and the
second parameter from the end set to 2, and again with all parameters zero
except the fd.
It then proceeds to read the file with InternetReadFile and fails. The update
is carried out much faster in wine than on windows.
