You have two problems here:

1a) The -a parameter enables active mode sessions. Which means the
'existing_users' ACL (or another ACL matching an 'accept button' URL)
has to pass "LOGIN" to the helper for sessions to exist.

1b) The ACL 'MyNetwork' is not used to deny anything, so the deny_info
has nothing to do.

2) you do not seem to have any logic to identify when a particular
request will be user-visible.
 This is kind of important since modern browsers and OS perform a huge
amount of automated requests in the background. Or even things with XHR
scripts during user browsing.
None of which the user will ever see in 'page' format, but which can
screw up the system or web service behaviour of the recipient software.
That 511 is the right way to do this, but is a fairly new feature in
HTTP so a lot of software still dont handle it well.
