Rewrite Rules

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

Log Level

Description

Specifies the level of detail of the rewrite engine's debug output. This value ranges from 0 - 9. 0 disables logging. 9 produces the most detailed log. The server and virtual host's error log Log Level must be set to at least INFO for this option to take effect. This is useful when testing rewrite rules.

Syntax

Integer number

Name

Description

Specifies a unique name for the rewrite map at the virtual host level. This name will be used by a mapping-reference in rewrite rules. When referencing this name, one of the following syntaxes should be used:

$\{MapName:LookupKey\}
$\{MapName:LookupKey|DefaultValue\}

The implementation of LiteSpeed's rewrite engine follows the specifications of Apache's rewrite engine. For more details about rewrite maps, please refer to Apache's mod_rewrite document.

Syntax

string

Location

Description

Specifies the location of the rewrite map using the syntax MapType:MapSource.
LiteSpeed's rewrite engine supports three types of rewrite maps:

  • Standard Plain Text
    MapType: txt;
    MapSource: file path to a valid plain ASCII file.
    Each line of this file should contain two elements separated by blank spaces. The first element is the key and the second element is the value. Comments can be added with a leading "#" sign.
  • Randomized Plain Text
    MapType: rnd;
    MapSource: file path of a valid plain ASCII file.
    File format is similar to the Standard Plain Text file, except that the second element can contain multiple choices separated by a "|" sign and chosen randomly by the rewrite engine.
  • Internal Function
    MapType: int;
    MapSource: Internal string function
    4 functions are available:
    • toupper: converts lookup key to upper cases.
    • tolower: converts lookup key to lower cases.
    • escape: perform URL encoding on lookup key.
    • unescape: perform URL decoding on lookup key.
  • The following map types available in Apache have not been implemented in LiteSpeed:
    Hash File and External Rewriting Program.
The implementation of LiteSpeed's rewrite engine follows the specifications of Apache's rewrite engine. For more details about rewrite map, please refer to Apache's mod_rewrite document.

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 .

GDPR Statement

LiteSpeed Technologies values your users’ privacy. Although our software does not directly collect any personally identifiable information from visitors to your site, LiteSpeed may still be considered a data processor, as user information may be temporarily cached and/or logged, as outlined in this document.

Servers

LiteSpeed Web Server, OpenLiteSpeed, LiteSpeed Web ADC, and related software may record IP addresses as a part of normal logging. An access log and an error log may record visitor IP addresses and URL visited. The logs are stored locally on the system where LiteSpeed server software is installed and are not transferred to or accessed by LiteSpeed employees in any way, except as necessary in providing routine technical support if you request it. This logging may be turned off through configuration. It is up to individual server administrators to come up with their own schedule for removing such logs from the file system.

Cache Solutions

Our cache plugins potentially store a duplicate copy of every web page on display on your site. The pages are stored locally on the system where LiteSpeed server software is installed and are not transferred to or accessed by LiteSpeed employees in any way, except as necessary in providing routine technical support if you request it. All cache files are temporary, and may easily be purged before their natural expiration, if necessary, via a Purge All command. It is up to individual site administrators to come up with their own cache expiration rules.

LSCache for WordPress

In addition to caching, our WordPress plugin has an Image Optimization feature. When optimization is requested, images are transmitted to a remote LiteSpeed server, processed, and then transmitted back for use on your site. LiteSpeed keeps copies of optimized images for 7 days (in case of network stability issues) and then permanently deletes them.

Similarly, the WordPress plugin has a Reporting feature whereby a site owner can transmit an environment report to our server so that we may better provide technical support.

Neither of these features collects any visitor data. Only server and site data is involved.

Support Services

Sometimes, when you request technical support, LiteSpeed may ask for login credentials to various areas of your site. You may refuse to share such credentials, however refusal may impact LiteSpeed’s ability to provide the requested support services.

Upon completion of a support ticket, LiteSpeed immediately deletes all login credentials you may have shared.

Any user data encountered by LiteSpeed is kept strictly confidential. We never provide your support ticket information to any third party without your explicit consent.

If you would like to update information that you have voluntarily provided to us, stop receiving information from us, or exercise any of the rights granted to you under Privacy Laws, including the EU’s General Data Protection Regulation, please e-mail info@litespeedtech.com.
