D7 Reverse proxy page migration

Could someone review the page and add it into the menu?

@O'Briat, thanks.

I scanned the new page and I didn't spot anything that requires a change.. Any further improvements can be made by the community on a on-going basis.

avpaderno → credited eelkeblok → .

The new page still needs to appear in the parent page menu : Installing Drupal →

I added it.

It appears after the other documentation pages. Should the order be changed?
