Load Balancer Context
Table of Contents
URI | Load Balancer | Realm | Authentication Name | Require (Authorized Users/Groups) | Access Allowed | Access Denied | Authorizer | Add Default Charset | Customized Default Charset | Enable IP Geolocation |
Load Balancer Context  |
| Description: Like other external applications, load balancer worker applications cannot be used directly. They must be mapped to a URL through a context. A Load Balancer Context will associate a URI to be load balanced by the load balancer workers. |
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. |
| See Also: Location |
Load Balancer |
| Description: Specifies the name of the load balancer to be associated to this context. This load balancer is a virtual application, and must be defined in the External Application section at the server or virtual host level. |
| Syntax: Select from drop down list |
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:
|
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: Sub-networks can be written as 192.168.1.0/255.255.255.0, 192.168.1, or 192.168.1.*. |
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: Sub-networks can be written as 192.168.1.0/255.255.255.0, 192.168.1, or 192.168.1.*. |
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. |
| Syntax: Select from drop down list |
Add Default Charset |
| Description: Specifies whether to add a character set tag to the "Content-Type" response header, when content type is either "text/html" or "text/plain" without any parameters. When set to Off, this function is disabled. When set to On, either the character set specified by Customized Default Charset or the default "iso-8859-1" will be added. |
| Syntax: Select from radio box |
Customized Default Charset |
| Description: Specifies a character set to be used when Add Default Charset is On. This is optional. The default value is iso-8859-1. This entry has no effect when Add Default Charset is Off. |
| Syntax: Name of a character set. |
| Example: utf-8 |
Enable IP Geolocation |
| Description: Specifies whether to enable/disable IP Geolocation lookup. Can be set at server, virtual host, or context level. IP Geolocation is disabled by default when using value "Not Set". |
| Syntax: Select from radio box |
| See Also: Use Client IP in Header, DB File Path, DB Cache Type |
