You can use the following 

acl NoSSLIntercept ssl::server_name_regex -i "/usr/local/pkg/reg.url.nobump"
acl NoBumpDNS dstdomain "/usr/local/pkg/dns.nobump"

I created a regex based no bump file and or use a dns based no bump file to mark splice only sites.

Example of what is in reg.url.nobump file

^((alt[0-9]-mtalk\.)|(mtalk\.)|(mtalk-(staging|dev)\.))google\.com

^((gvt)([0-9]))\.com

^(((clients)[0-9])|accounts)\.google\.(com|us)

^(pki|(crl|ocsp)\.pki)\.google\.com

(outlook\.)(office365|office)\.com

infinity-c[0-9][0-9]\.youboranqs[0-9][0-9]\.com

hulu\.com

nflxvideo\.net

Or example of what could be in dns.nobump

.play.google.com

.android.com

.google-analytics.com

.googleusercontent.com

.ggpht.com

.dl.google.com

.dl-ssl.google.com

.android.clients.google.com

.omahaproxy.appspot.com

.payments.google.com

.googleapis.com

.notifications.google.com

.ogs.google.com

.googleapis.com

Make sure you follow the enterprise policy for Google Android based products. 

Some sites simply can not and or should not be bumped and you only should look at the get header.

I apologize for the formatting of the text of the letter?

I will be incorrect if I do not say that there are entries in the cache.log, although the IP does not resolve directly to google subdomains, but according to whois, this is the Google LLC farm.

Have you created a splice only file with lists of items that must be spliced at all times, Google mail ethically should be spliced just as an example. Some know sites must be spliced.
