Links from subdomain to WWW domain unconditionally overridde

I put a link into a content block on a development server.

The dev server base URL is
dev.example.com

The link I entered goes to 
www.production.com/page

When I pushed the site live to:
subdomain.production.com

The link in my content block updated itself automatically to:
subdomain.production.com/page

I tried changing it back to:
www.production.com/page

but SiteFinity re-writes it to
subdomain.production.com/page 


I then tried putting a javascript block, and told the script to reassign the href to:
www.production.com/page 

But even the Javascript block gets rewritten by SiteFinity to
subdomain.production.com/page 


This is very bad.  We need to have the ability to link to www.production.com from subdomain.production.com

Why is that not possible?  What can I do to stop Sitefinity from changing my links like this?

I also have this issue and need it resolved.  What can we do to stop Sitefinity from changing  links like this?
