Hi,
  The 'webpdb' plugin creates a new Tcl interpreter instance, which
has the effect that it does not inherit or alter any state within the
main VMD Tcl interpreter. You could recompile the webpdb plugin to
force it to use a proxy if necessary, it would be a matter of modifying
the source code to run an extra Tcl_Eval() call to perfom the proxy
setup akin to what you ran in the main VMD Tcl interpreter.
If you're interested in trying this, I could probably make a modified version
that does this for you.

Cheers,
  John Stone
