Since not all HTTP servers support version 1.1 of the
HTTP protocol, this property can be used to specify a lower
version (or even greater) when establishing a connection
with a server. However, different protocol versions mean a
different flow of information, so the user is responsible
for manually responding to any event that is not supported
by version 1.1.
If a version lower than 1.1 is used, do not try to use
pipelined requests (multiple requests on the same server
without disconnecting), because unexpected results may
occur.
