request can't follow redirect URLs with inline ports in them

possible_patch.js

/* Making the following amendment to options.start in main.js causes this issue to cease.
   I believe this is due to some kind of caching taking place in the agent layer.  I also believe
   that we have a situation here where each callback is getting invoked multiple times.
