Each POST attempt will decrease the number of remaining attempts by 1, with the number of remaining attempts increasing back to the set limit over time.

You would want to allow those connections for a short period.&lt;br/&gt;&lt;br/&gt; HTTP/1.1 clients may also set up multiple connections to speed up downloading and SSL  requires separate connections from non-SSL connections.

For example, to prohibit serving PHP scripts in a directory that is group and world writable, set the mask to &lt;span class=&quot;val&quot;&gt;022&lt;/span&gt;. Default value is &lt;span class=&quot;val&quot;&gt;000&lt;/span&gt;. This option can be used to prevent serving scripts under a directory of  uploaded files.&lt;br/&gt;&lt;br/&gt; See &lt;span class=&quot;cmd&quot;&gt;man 2 stat&lt;/span&gt; for all values.&lt;/p&gt; &lt;h4&gt;Syntax&lt;/h4&gt;&lt;p&gt;octal numbers&lt;/p&gt; &lt;h4&gt;See Also&lt;/h4&gt;&lt;p class=&quot;ls-text-small&quot;&gt;&lt;span class=&quot;tagl&quot;&gt;&lt;a href=&quot;#restrictedScriptPermissionMask&quot;&gt;Script Restricted Permission Mask&lt;/a&gt;&lt;/span&gt;.&lt;/p&gt; &lt;/article&gt; &lt;/div&gt;

Memory and process limits also serve as the default for other external applications if limits have not been set explicitly for those applications.&lt;/p&gt; &lt;/article&gt; &lt;/div&gt;

LiteSpeed server uses a standalone CGI daemon to spawn CGI scripts for best performance and security. If you need to change this location, specify a Unix domain socket here.&lt;br/&gt;&lt;br/&gt; Default value: &lt;span class=&quot;val&quot;&gt;uds://$SERVER_ROOT/admin/lscgid/.cgid.sock&lt;/span&gt;&lt;/p&gt; &lt;h4&gt;Syntax&lt;/h4&gt;&lt;p&gt;UDS://path&lt;/p&gt; &lt;h4&gt;Example&lt;/h4&gt;&lt;div class=&quot;ls-example&quot;&gt;UDS://tmp/lshttpd/cgid.sock&lt;/div&gt;&lt;/article&gt; &lt;/div&gt;

For each request to a CGI script, the server needs to start a standalone CGI process. On a Unix system, the number of concurrent processes is limited. Excessive concurrent processes will degrade the performance of the whole system and are one way to perform a DoS attack. LiteSpeed server pipelines requests to CGI scripts and limits concurrent CGI processes to ensure the optimal performance and reliability. The hard limit is &lt;span class=&quot;val&quot;&gt;2000&lt;/span&gt;.&lt;/p&gt; &lt;h4&gt;Syntax&lt;/h4&gt;&lt;p&gt;Integer number&lt;/p&gt; &lt;h4&gt;Tips&lt;/h4&gt;&lt;p&gt;&lt;span title=&quot;Security&quot; class=&quot;ls-icon-security&quot;&gt;&lt;/span&gt;&lt;span title=&quot;Performance&quot; class=&quot;ls-icon-performance&quot;&gt;&lt;/span&gt; A higher limit does not necessarily translate to faster performance. In most cases, a lower limit gives better performance and security. A higher limit will only help when I/O latency is excessive during CGI processing.&lt;/p&gt; &lt;/article&gt; &lt;/div&gt;

When set to non-zero value, all suEXEC external applications (CGI/FastCGI/LSAPI) will use this group ID. This can be used to prevent an external application from accessing files owned by other users.&lt;br/&gt;&lt;br/&gt; For example, in a shared hosting environment, LiteSpeed runs as user &quot;www-data&quot;, group &quot;www-data&quot;. Each docroot is owned by a user account, with a group of &quot;www-data&quot; and permission mode 0750. If Force GID is set to &quot;nogroup&quot; (or any group other than 'www-data'), all suEXEC external applications will run as a particular user but in the group &quot;nogroup&quot;. These external application processes will still be able to access files owned by that particular user (because of their user ID), but will not have group permission to access anyone else's files. The server, on the other hand, still can serve files under any user's docroot directory (because of its group ID).&lt;/p&gt; &lt;h4&gt;Syntax&lt;/h4&gt;&lt;p&gt;Integer number&lt;/p&gt; &lt;h4&gt;Tips&lt;/h4&gt;&lt;p&gt;&lt;span title=&quot;Security&quot; class=&quot;ls-icon-security&quot;&gt;&lt;/span&gt; Set it high enough to exclude all groups used by system users.&lt;/p&gt; &lt;/article&gt; &lt;/div&gt;

See &lt;span class=&quot;cmd&quot;&gt; man 2 umask &lt;/span&gt; for details. This also serves as the default value for external applications &lt;span class=&quot;tagl&quot;&gt;&lt;a href=&quot;ExtApp_Help.html#extUmask&quot;&gt;umask&lt;/a&gt;&lt;/span&gt;.&lt;/p&gt; &lt;h4&gt;Syntax&lt;/h4&gt;&lt;p&gt;value valid range [000]-[777].&lt;/p&gt; &lt;h4&gt;See Also&lt;/h4&gt;&lt;p class=&quot;ls-text-small&quot;&gt;ExtApp &lt;span class=&quot;tagl&quot;&gt;&lt;a href=&quot;ExtApp_Help.html#extUmask&quot;&gt;umask&lt;/a&gt;&lt;/span&gt;&lt;/p&gt; &lt;/article&gt; &lt;/div&gt;

Value ranges from &lt;span class=&quot;val&quot;&gt;-20&lt;/span&gt; to &lt;span class=&quot;val&quot;&gt;20&lt;/span&gt;. A lower number means a higher priority.&lt;br/&gt;&lt;br/&gt; A CGI process cannot have a higher priority than the web server. If this priority is set to a lower number than the server's, the server's priority will be used for this value.&lt;/p&gt; &lt;h4&gt;Syntax&lt;/h4&gt;&lt;p&gt;int&lt;/p&gt; &lt;h4&gt;See Also&lt;/h4&gt;&lt;p class=&quot;ls-text-small&quot;&gt;Server &lt;span class=&quot;tagl&quot;&gt;&lt;a href=&quot;ServGeneral_Help.html#serverPriority&quot;&gt;Priority&lt;/a&gt;&lt;/span&gt;&lt;/p&gt; &lt;/article&gt; &lt;/div&gt;

Make sure to leave enough head room, otherwise your application may fail and 503 error may be returned. It can be set at the server- level or at an individual external application level. The server-level limit will be used if it is not set at the individual application level.&lt;br/&gt;&lt;br/&gt; The operating system's default setting will be used if the value is absent at both levels or set to &lt;span class=&quot;val&quot;&gt;0&lt;/span&gt;.&lt;/p&gt; &lt;h4&gt;Syntax&lt;/h4&gt;&lt;p&gt;Integer number&lt;/p&gt; &lt;h4&gt;Tips&lt;/h4&gt;&lt;p&gt;&lt;span title=&quot;Attention&quot; class=&quot;ls-icon-attention&quot;&gt;&lt;/span&gt; Do not over adjust this limit.

All existing processes will be counted against this limit, not just new processes to be started.&lt;br/&gt;&lt;br/&gt; The limit can be set at the server level or at an individual external application level. The server-level limit will be used if it is not set at an individual application level.

PHP scripts can call for forking processes and the number of processes needed for normal functioning can be above the suEXEC Max Conn setting. The main purpose of this limit is as a last line of defense to prevent fork bombs and other attacks caused by PHP processes creating other processes.&lt;br/&gt;&lt;br/&gt; Setting this setting too low can severely hurt functionality. The setting will thus be ignored below certain levels.&lt;br/&gt;&lt;br/&gt; When &lt;b&gt;Run On Start Up&lt;/b&gt; is set to &quot;Yes (Daemon mode)&quot;, the actual process limit will be higher than this setting to make sure parent processes are not limited.&lt;/p&gt; &lt;/article&gt; &lt;/div&gt;

Once active, all requests by NON TRUSTED(as configured) clients will be redirected to a reCAPTCHA validation page. After validation, the client will be redirected to their desired page.&lt;br/&gt;&lt;br/&gt; The following situations will activate reCAPTCHA Protection:&lt;br/&gt; 1. The server or vhost concurrent requests count passes the configured connection limit.&lt;br/&gt; 2. Anti-DDoS is enabled and a client is hitting a url in a suspicious manner. The client will redirect to reCAPTCHA first instead of getting denied when triggered.&lt;br/&gt; 3. WordPress Brute Force Attack Protection is enabled and action is set to 'CAPTCHA or Drop’. When a brute force attack is detected, the client will redirect to reCAPTCHA first. After max tries is reached, the connection will be dropped, as per the ‘drop’ option.&lt;br/&gt; 4. WordPress Brute Force Attack Protection is enabled and action is set to 'WP Login CAPTCHA Full Protection'. The client will always redirect to reCAPTCHA first.&lt;br/&gt; 5. A new rewrite rule environment is provided to activate reCAPTCHA via RewriteRules. 'verifycaptcha' can be set to redirect clients to reCAPTCHA. A special value ': deny' can be set to deny the client if it failed too many times. For example, [E=verifycaptcha] will always redirect to reCAPTCHA until verified. [E=verifycaptcha: deny] will redirect to reCAPTCHA until Max Tries is hit, after which the client will be denied.&lt;/p&gt; &lt;/article&gt; &lt;/div&gt;

The setting of the smallest scope that fits for an IP will be used to determine access.&lt;br/&gt;&lt;br/&gt; &lt;b&gt;Server Level:&lt;/b&gt; Trusted IPs or sub-networks must be specified in the &lt;span class=&quot;tagl&quot;&gt;&lt;a href=&quot;#accessControl_allow&quot;&gt;Allowed List&lt;/a&gt;&lt;/span&gt; by adding a trailing &quot;T&quot;.
