If they provide the wrong oauth state code, tell the user the correct one!

And of course,in production, it always reported success and never changed the password, because of equally bad server code.

boolVALUE != !1 && dtTEXTVALUE.indexOf('http://') != -1 && (dtTEXTVALUE = dtTEXTVALUE.replace('http://','')) && dtTEXTVALUE.indexOf('.aspx') == -1 && (dtTEXTVALUE += '.aspx');

return dtTEXTVALUE;

}

Here's the weirdest way to create if statement with terrible naming conventions. Its based on real events and production code.
