Maybe first, understand that this has nothing to do with Tomcat.  So you may have been 
looking for information in the wrong places.

It is your application making a connection to some outside endpoint, and Tomcat knows 
nothing about it.
The only thing in common between your application and Tomcat, is that they both run in the 
same JVM.
So if you set a global JVM option "-D", this impacts *everything* that runs in that JVM : 
Tomcat, other applications, and your own application.

You probably need to find a way to set these properties for your application only (or for 
that connection only).
Sadly, I don't know java well-enough to know if that is possible in this case.
What library are you using, to make that HTTP call ?  Look there first.
