@amitkdutta can you please help review? Thanks.

@majetideepak : Is it possible to add a check in some test in https://github.com/prestodb/presto/blob/master/presto-native-execution/presto_cpp/main/tests/PrestoExchangeSourceTest.cpp, so that we can be assured that this field continues to output in header and is not accidentally dropped by someone else.

Else this PR is good, I'll approve it once the test is in place.

@aditi-pandit We need to setup https with certain versions of packages. We don't have such a framework.

I also don't see a way to get the doRequest headers in this test as well. PrestoExchangeSourceTest.cpp

[aditi-pandit]

You should be able to get host header from message parameter here (its unused now): https://github.com/prestodb/presto/blob/master/presto-native-execution/presto_cpp/main/tests/PrestoExchangeSourceTest.cpp#L135

We can add a check that it always has a host:port format.

@aditi-pandit can you take a look now? I added a test. Thanks.
