[edk2-devel] HttpProtocol->request blocks execution

[edk2-devel] HttpProtocol->request blocks execution

After configuring the HTTP Protocol, creating the event for the callback
and filling all the necessary fields on the request token, I'm using :


*.... Status = HttpProtocol->Request(HttpProtocol, &RequestToken);*

* Print(L"Only gets printed after Request is successful");*
*....*

To start the HTTP request. This code is being compiled as a UEFI
Application and run via UEFI SHELL using the QEMU emulator.

The http request works as expected when the host is responsive, however,
when the host is unreachable (for example offline), the execution just
hangs for more than 2 minutes, eventually returning with a Status code of
EFI_TIME_OUT.

I have tried reducing the timeout interval by defining

*....ConfigData->TimeOutMillisec    = 5000;*

*Status = HttpProtocol->Configure(HttpProtocol, ConfigData);....*

But this doesn't seem to change the behaviour of the request function.

Why is HttpProtocol->request blocking execution and not following the event
pattern, and how could I customize the timeout interval?

Any feedback much appreciated, thank you!
