| - | LiteSpeed Web Server version 5.0 introduces virtual host-level bandwidth throttling. This can be thought of as an extension of LSWS's [[http://www.litespeedtech.com/docs/webserver/config/security#perClientConnLimit|Per Client Throttling settings]], which allow you to control the amount of stress a single IP can put on your server. Virtual host-level bandwidth throttling allows you to customize bandwidth throttling, in Apache configs, for particular virtual hosts. This allows you to set up stricter settings for sites that you know are targets or more lenient settings for sites that might require a lot of bandwidth going to one IP. (This has been available for some time in vhosts with LSWS-native configs.) It also allows for throttling bandwidth by file type and size. | + | LiteSpeed Web Server version 5.0 introduces virtual host-level bandwidth throttling.

| LSWS's implementation of this bandwidth throttling follows syntax similar to that used by Apache’s [[http://bwmod.sourceforge.net/files/mod_bw-0.7.txt|mod_bw]]. Bandwidth throttling directives can only be placed in virtual host configuration file, not an .htaccess file. | LSWS's implementation of this bandwidth throttling follows syntax similar to that used by Apache’s [[http://bwmod.sourceforge.net/files/mod_bw-0.7.txt|mod_bw]].

| + | |||
| + | **Note:** LSWS simply lowers bandwidth as users get close to limits. It does not return error pages. | ||
| ===== Directives ===== | ===== Directives ===== | ||
| + | |||
| + | ==== VhostBandwidthLimit ==== | ||
| + | |||
| + | Syntax: | ||
| + | |||
| + | VhostBandwidthLimit [Speed in bytes/s] | ||
| + | |||
| + | The ''VhostBandwidthLimit'' directive controls the amount of bandwidth allotted to a virtual host regardless of the number of concurrent visitors. It can only be set at the virtual host level in the Apache configuration file or through Apache-style config in native LSWS configuration. | ||
| + | |||
| + | It takes 1 parameter: | ||
| + | |||
| + | * ''Speed'' indicates the total speed available to the virtual host. If ''Speed'' is less than ''4097'', there is no limit. | ||

| * ''Type'' is the suffix of files to be throttled. ''*'' can be used to designate all files. | * ''Type'' is the suffix of files to be throttled. ''*'' can be used to designate all files. | ||
| - | * | + | * ''Minimum Size'' tells the server the size of files to be throttled. |
| + | * ''Speed'' indicates the maximum speed at which these files can be served. | ||
| + | |||
| + | ==== MaxConnPerClient ==== | ||
| + | |||
| + | Syntax: | ||
| + | |||
| + | MaxConnPerClient <limit_for_connections> | ||
| + | |||
| + | The MaxConnPerClient directive allows you to configure the maximum concurrent connections from one IP. | ||
| + | * ''limit_for_connections'' set the connection limit. | ||
| + | ===== Examples ===== | ||
| + | |||
| + | BandWidth all 102400 | ||
| + | |||
| + | The above setting would limit the total bandwidth allowed to this virtual host to 100KB/s | ||
| + | |||
| + | BandWidth all 50000 | ||
| + | MinBandWidth all -1 | ||
| + | LargeFileLimit .avi 500 10240 | ||
| + | |||
| + | The above settings limit each client to 50KB/s with no maximum total bandwidth. .avi files of 500KB or greater, though, are limited to 10KB/s. | ||
