Lets say I want to GET one byte from a server using the HTTP protocol and I want to minimize everything. No headers just http://myserver.com/b, where b is a text file with one character in it, or better still b is just one character (not sure if that is possible).
Is there a way to do this with Apache and what is the smallest possible amount of data that is required for complete http and, complete HTTPS transactions?
Alternatively, the transaction could be done with just a head request if that is more data efficient.
