I need to change this parameters, like:

is_rooted%22%3Atrue into is_rooted%22%3Afalse

I'l try use this:

if (oSession.PathAndQuery("sitel.com:443")){
              oSession["ui-backcolor"] = "lime";
              oSession.utilDecodeResponse();
              oSession.utilReplaceInResponse('is_rooted%22%3Atrue','is_rooted%22%3Afalse');
          }

 

But it's not work.

I'll try this to fix https and modify request:
But it's not work again...

    if (oSession.HostnameIs("sitel.com")) {
                oSession["ui-backcolor"] = "lime";
              oSession.utilDecodeResponse();
              oSession.utilReplaceInResponse('is_rooted%22%3Atrue','is_rooted%22%3Afalse');
}
