Default local cache path (short-form server string) #15
Description
Symchk supports specifying just a symbol server URL, with the expectation that it will download symbols from that URL and cache them to a pre-determined cache path.
For example, the "server string" https://msdl.microsoft.com/download/symbols will get implicitly expanded to SRV**https://msdl.microsoft.com/download/symbols, which is expanded to SRV*C:\ProgramData\dbg\sym*https://msdl.microsoft.com/download/symbols.
