Mate, redirections has nothing to do with change. Changing/Renaming something WON'T make it redirect.
thats exactly what one of the many purposes of the .htaccess is used for, to redirect to ssl from non-ssl and other way around, changing it on file causes the url to redirect :fp:
Here let me give you an example so that you can understand that what your saying makes absolutely no sense.
# (is not important if comes with or without https):
So changing/Renaming something WILL and canmake a URLredirect elsewhere. Need more examples?
His problem can be solved here or in his C panel if he had a problem with his own website URL, if he wanted to change from sub domain to sub directory and I thought that was what he was asking help for.
I didn't know he had a problem with another guys URL that he used in his iframes, by the time he specifically said that you already jumped in with your false claims ..
