Hello,
This patch introduces a new 'auth_schemes' squid.conf directive.
This directive may be used to customize authentication
schemes presence and order in Squid's HTTP 401 (Unauthorized) and 407
(Proxy Authentication Required) responses. The defaults remain the same.
Also refactored configuration code for options with custom
ACL-controlled actions:
* Reduced parsing code duplication by adding ParseAclWithAction().
* Used functors for generic action-to-string conversions. It is possible
now to perform such conversions providing lambda expressions.
* Used vectors of strings instead of C-style arrays for storing
conversion tables and check against bounds with vector::at().
Regards,
Eduard.
Added auth_schemes to control schemes presence and order in 401s/407s.

If you use proxy authentication and the 'max_user_ip' ACL,
this directive controls how long Squid remembers the IP
addresses associated with each user. Use a small value
(e.g., 60 seconds) if your users might change addresses
quickly, as is the case with dialup. You might be safe
using a larger value (e.g., 2 hours) in a corporate LAN
environment with relatively static address assignments.

+
+ A special "ALL" scheme name expands to all auth_param-configured

+ to configure Squid to offer no authentication schemes at all.
+
+ The first matching auth_schemes rule determines the schemes order
+ for the current Authentication Required transaction. Note that the
+ future response is not yet available during auth_schemes evaluation.
+
+ If this directive is not used or none of its rules match, then Squid
+ responds with all configured authentication schemes in the order of
+ auth_param directives in the configuration file.
+
+ This directive does not determine when authentication is used or
+ how each authentication scheme authenticates clients.
+
+ The following example sends basic and negotiate authentication
