The function is implemented by setting cache file pointer to fill read_buf. Consequently, when HTTPREQ_ReadFile is called, it will try reading data from cache after read_buf is depleted, before continuing reading from http stream.

Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:

It seems the tests on 32-bit debian is failing due to cache file handle being invalid, but I'm unable to reproduce the problem.
