# uWSCGI Context

### uWSGI Context

#### Description

uWSGI applications cannot be used directly. A uWSGI application must be either configured as a script handler or mapped to a URL through a uWSGI context. A uWSGI context will associate a URI with an uWSGI application.

### 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.

Location

### uWSGI App

#### Description

Specifies the name of the uWSGI application. This application must be defined in the External Apps section at the server or virtual host level.

#### Syntax

Select from drop down list

### 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

set Cache-control no-cache
append Cache-control no-store
Header set My-header cust_header_val
RequestHeader set My-req-header cust_req_header_val

#### Tips

Information Syntax and usage are similar to Apache's mod_headers directives for supported operations.
Information 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.

If this setting is not specified, all valid users will be allowed to access this resource.

### 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 https://fastcgi-archives.github.io/ .

#### Syntax

### 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

### 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
