You are an idiots with grand XY-troubles. Question was: how to show .hta file from .html w/o downloading it. Author didn't ask You about accessibility hta in browser - he did ask HOW TO DO? I develop .hta application and need normal simple and lightaccesible instrument for debug interface part. I need load/reload .hta in browser w/o rename file into .html each time for debugging. Can anybody reset youself brains from narcissism mode to work state and simply answer for question?
