Static Context⇑
Description
Context settings are used to specify special settings for files in a certain location. These settings can be used to bring in files outside of the document root (like Apache's Alias or AliasMatch directives), to protect a particular directory using authorization realms, or to block or restrict access to a particular directory within the document root.
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⇑
Description
Specifies the corresponding location of this context in the file system.
Default value: $DOC_ROOT + URI
Syntax
It can be an absolute path or path relative to $SERVER_ROOT, $VH_ROOT, or $DOC_ROOT. $DOC_ROOT is the default relative path, and can be omitted.
If the URI is a regular expression, then the matched sub-string can be used to form the "Root" string. The matched sub-string can be referenced with the values "$1" - "$9". "$0" and "&" can be used to reference the whole matched string. Additionally, a query string can be set by appending a "?" followed by the query string. Be careful. "&" should be escaped as "\&" in the query string.
Example
To simulate Apache's mod_userdir, set URI to exp: ^/~([A-Za-z0-9]+)(.*), set Location to /home/$1/public_html$2. With these settings, a request of URI /~john/foo/bar.html will map to file /home/john/public_html/foo/bar.html.

Accessible⇑
Description
Specifies whether this context can be accessed. Set to No to deny access. You can use this feature to protect the specified directory from being visited. You may use it when you are updating contents for this context or you have special data in this directory.
Syntax
Select from radio box
Enable Expires⇑
Description
Specifies whether to generate an Expires header for static files. If enabled, an Expires header will be generated based on Expires Default and Expires By Type.
This can be set at server, virtual host and context level. Lower level settings will override higher level ones, i.e. context settings will override virtual host settings and virtual host settings will override server settings.
Syntax
Select from radio box
Expires Default⇑
Description
Specifies default settings for Expires header generation. This setting takes effect when Enable Expires is set to "Yes". It can be overridden by Expires By Type. Do not set this default at the server or virtual host level unless you have to, since it will generate Expires headers for all pages. Most of time this should be set at the context level for certain directories that do not change often. If there is no default setting, no Expires header will be generated for types not specified in Expires By Type.
Syntax
A|Mseconds
The file will expire after base time(A|M) plus specified seconds. Base time "A" sets the value to the client's access time and "M" to the file's last modified time.
Expires By Type⇑
Description
Specifies Expires header settings for individual MIME types.
Syntax
Comma delimited list of "MIME-type=A|Mseconds". The file will expire after base time (A|M) plus specified seconds.
Base time "A" sets the value to the client's access time and "M" to the file's last modified time. MIME-type accepts wildcard "*", like image/*.
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.
MIME Type⇑
Description
Specifies additional MIME types and mappings for this context. New mappings will override existing mappings under this context and its children contexts.
If you want to show PHP scripts as text files instead of being executed as scripts, just override the .php mapping to MIME type "text/plain".
Syntax
MIME-type1 extension extension ..., MIME-type2 extension ... Use comma to separate between MIME types, use space to separate multiple extensions.
Example
Force MIME Type⇑
Description
When specified, all files under this context will be served as static files with the MIME type specified regardless of file suffix. When set to NONE, inherited force type setting will be disabled.
Syntax
MIME type or NONE.
Default MIME Type⇑
Description
When specified, this type will be used when MIME type mapping cannot be determined by the suffix of a document or if there is no suffix. If not specified, the default value application/octet-stream will be used.
Syntax
MIME-type
Index Files⇑
Description
Specifies names of index files that will be searched sequentially when a URL is mapped to a directory. You can customize it at the server, virtual host, and context level.
Syntax
Comma-delimited list of index filenames.
Tips
Only set index files that you need.
Auto Index⇑
Description
Specifies whether to generate a directory index on the fly when index files listed in Index Files are not available in a directory. This option is customizable at the virtual host and context level, and is inherited along the directory tree until it is explicitly overridden. You can customize the generated index page. Please check online wiki How-tos.
Syntax
Select from radio box
Tips
It is recommended to turn off Auto Index wherever possible to prevent revealing confidential data.

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.
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
Enable Rewrite⇑
Description
Specifies whether to enable LiteSpeed's URL rewrite engine. This option can be customized at the virtual host or context level, and is inherited along the directory tree until it is explicitly overridden.
Syntax
Select from radio box
Rewrite Inherit⇑
Description
Specifies whether to inherit rewrite rules from parent contexts. If rewrite is enabled and not inherited, rewrite base and rewrite rules defined in this context will be used.
Syntax
Select from radio box
Rewrite Base⇑
Description
Specifies the base URL for rewrite rules.
Syntax
URL
Rewrite Rules⇑
Description
Specifies a list of rewrite rules at the virtual host level.
Do NOT add any document root level rewrite rules here. If you have any document root level rewrite rules from .htaccess, you should instead create a static context with uri "/" and add the rewrite rules there.
A rewrite rule is comprised of one RewriteRule directive and optionally preceded by multiple RewriteCond directives.
- Each directive should take only one line.
- RewriteCond and RewriteRule follow Apache's rewrite directive syntax. Just copy and paste rewrite directives from your Apache configuration files.
- There are minor differences between LiteSpeed and Apache mod_rewrite implementation:
- %\{LA-U:variable\} and %\{LA-F:variable\} are ignored by the LiteSpeed rewrite engine
- Two new server variables are added in the LiteSpeed rewrite engine: %\{CURRENT_URI\} represents the current URI being processed by the rewrite engine and %\{SCRIPT_NAME\} has the same meaning as the corresponding CGI environment variable.
- The LiteSpeed rewrite engine will stop processing rewrite rules after encountering an [L] flag to avoid looping while Apache mod_rewrite will stop processing rewrite rules for the current iteration only. This behavior is similar to that of the [END] flag in Apache mod_rewrite.
The implementation of LiteSpeed's rewrite engine follows Apache's rewrite engine specifications. For more details about rewrite rules, please refer to Apache's mod_rewrite document and Apache's URL rewriting guide .
Syntax
string
Enable GeoLocation Lookup⇑
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

php.ini Override⇑
Description
Used to overwrite php.ini settings in the current context (Virtual Host level or Context level).
Supported directives are:
php_value
php_flag
php_admin_value
php_admin_flag
All other lines/directives will be ignored.
Syntax
Override syntax is similar to Apache, a newline separated list of directives and their values with each directive being prepended by php_value, php_flag, php_admin_value, or php_admin_flag appropriately.
Example
php_admin_flag engine on
php_admin_value open_basedir "/home"
