SharePoint 2013, F5 and SSL Offload

Hi Mike, sorry for late response to your suggestions. I managed to get SSL Offload working and search working by using the new SharePoint 2013 cmdlet (Post March 2013 PU) Set-SPSiteURL on all host named site collections.

I was able to add an "internet" zone URL mapping by doing the following:

Example only:

Set-SPSiteURL -identity http://hostnamedsite.contoso.com -Url https://hostnamedsite.contoso.com -Zone Internet

Our default zone URL was HTTP

I then followed the F5 guide, adding the Web Application's default Public HTTPS url into the search content source address list.

It now appears to work.

Thanks for your help.
