Hi Gary,
First off I'll recommend you to clean up the URL and redirect command from your 443 rules, as 443 is encrypted the CSS is not able to look at layer 5 info within the traffic, making this commands useless for these rules.
That being said; since you're using SSL termination your configuration for HTTPS-to-HTTPS redirect would look like this:
content Sharepoint_https
vip address 10.4.16.54
application ssl
advanced-balance ssl
flow-timeout-multiplier 10
add service ssl_sharepoint
port 443
protocol tcp
active
content Sharepoint_https_redirect
vip address 10.4.16.54
port 80
protocol tcp
url "/*"
redirect "https://10.4.16.54/AHC/SitePages/Home.aspx"
active
content Sharepoint_http_Aspx
vip address 10.4.16.54
port 80
advance-balance arrowpoint-cookie
add service Sharepoint-1
add service Sharepoint-2
protocol tcp
url "/AHC/SitePages/Home.aspx"
active
Here I'm assuming that you're not using backend SSL and your clear port is 80
Basically, traffic comes as https://10.4.16.54, hits the encrypted rule that send the traffic to the SSL proxy list for decryption, once decrypted traffic is sent to the clear text content rule, since there's no URI the request matches the rule with the wildcard URL "/*". This rule performs a redirect an indicates to the client to come back this time with the URI described ... process starts all over but this time the request will match the second clear text rule as the URI is more specific.
