PDB QUESTION

[zijingsh]

Hello to bother you again ： In China, Microsoft's symbolic parsing server always has some people who cannot link to the server, or cannot download ntkrnlmp.pdb, whose file size is 3KB and incomplete, I want to set a proxy server URL to cache and help customers download. However, I do not know where the change can be made to use the new address to download the operation when the download is incomplete. Second question, if there is info.db in the same directory, can I not download pdb from the symbol server in most cases Please forgive my poor English expression, I hope you can understand my meaning

I don't think the Microsoft symbol server libraries I use support a proxy server. They are quite old and I use those due to more restrictive licensing terms on newer versions (I don't know if the newer versions support proxy server either).

For most use cases I think the info.db should be sufficient though. I usually update it 2-3 days after patch Tuesday every month.

i test my pdb proxy is work，Now I want to know how to change the download address, or if he fails to download the pdb, how do I call him to re-download it with a different download address resolution thx u help ufrisk

On Windows, which I assume you're running on, I use the symsrv.dll from Microsoft.

I don't think it's capable of proxy servers, but you could look into the documentation, maybe it is possible somehow, or contact Microsoft about it.

If there is something I'd have to do to change MemProcFS to make it work please let me know. But I unfortunately don't think it's supported.
