And other programs, like bluestacks, have no support for proxy at all.īut you can force BlueStacks to go through the fiddler proxy. Some programs ignore wininet config completly and have their own method of setting a proxy (like firefox, chrome). You see, fiddler configures the winINET proxy to go through it (the one used by internet explorer and all other microsoft software, but sometimes even third pary software uses winINET proxy config - that is why some programs just magically work with fiddle).
