By default Internet Explorer converts all URLs in hyperlinks (anchor tags) and images (img tags) to absolute URLs. That's the reason you always get local server name before all A and IMG tags.

 

When this property is set to true (the default), CuteEditor strips out the local server name from all A and IMG tags if the hostname in the URL matches the current hostname on the server side.

 

So when you submit the form, the content goes into the database should not have the local server name.
