Proxy Context⇑
Description
A Proxy Context enables this virtual host as a transparent reverse proxy server. This proxy server can run in front of any web servers or application servers that support HTTP protocol. The External web server that this virtual host proxies for has to be defined in External Apps before you can set up a Proxy Context.
URI⇑
Description
Specifies the URI for this context.
Syntax
The URI can be a plain URI (starting with "/") or a Perl compatible regular expression URI (starting with "exp:"). If a plain URI ends with a "/", then this context will include all sub-URIs under this URI. If the context maps to a directory on the file system, a trailing "/" must be added.

Header Operations⇑
Description
Specifies additional response/request headers to be added. Multiple header directives can be added with one directive per line. "NONE" can be used to disable parent header inheritance. If no directive is provided 'Header' is assumed.
Syntax
[Header]|RequestHeader [condition] set|append|merge|add|unset header [value] [early|env=[!]variable]
Example
append Cache-control no-store
Header set My-header cust_header_val
RequestHeader set My-req-header cust_req_header_val
Tips
Syntax and usage are similar to Apache's mod_headers directives for supported operations.
The 'Header' directive is is optional and can be excluded or left in when copying rules from elsewhere without issue.
Realm⇑
Description
Specifies the authorization realm for this context. When specified, a valid username and password must be provided in order to access this context. Authorization Realms are set up in the Virtual Host Security section. This setting uses each realm's Realm Name.
Syntax
Select from drop down list
Authentication Name⇑
Description
Specifies an alternative name for the authorization realm for the current context. If not specified, the original realm name will be used. The authentication name is displayed on the browser's login pop-up.
Require (Authorized Users/Groups)⇑
Description
Specifies which user/group can access this context. This allows you to use one user/group database (specified in Realm) across a number of contexts, but only allow certain users/groups from that database to access this context.
Syntax
Syntax is compatible with Apache's Require directive. For example:
- user username [username ...]
Only listed users can access this context. - group groupid [groupid ...]
Only users belonging to the listed groups can access this context.
Access Allowed⇑
Description
Specifies which IPs or sub-networks are allowed to access resources under this context. Together with Access Denied and server/virtual host level access control, accessibility is determined by the smallest scope that a client's IP address falls into.
Syntax
Comma-delimited list of IPs/sub-networks.
Example
Access Denied⇑
Description
Specifies which IPs or sub-networks are NOT allowed to access resources under this context. Together with Access Allowed and server/virtual host-level access control, accessibility is determined by the smallest scope that a client's IP address falls into.
Syntax
Comma-delimited list of IPs/sub-networks.
Example
Authorizer⇑
Description
Specifies an external application that can be used to generate authorized/unauthorized decisions. Currently, only the FastCGI Authorizer is available. For more details about the FastCGI Authorizer role, please visit http://www.fastcgi.com.
