[SR-Users] remove_hf("Bla") for all requests

[Sergiu Pojoga]

That's right Amar.

Not planning to limit on removing one header only, I said strict, not light
diet, lol.

For now below ones, pretty sure other 'junk' headers will follow. As the
article mentions, one must be cautious though what to remove. Stage #2 will
be stripping off SDP junk,

remove_hf("Date");
remove_hf("Timestamp");
remove_hf("User-Agent");
remove_hf("Organization");
remove_hf("Server");
remove_hf("Allow");
