Some Magento plugins or operations may need to run very long php procceses but they may be killed by Litespeed Web Server with error 500 after 120 seconds. For example is SOAP API from witch you can update products. In this case Litespeed can detect the connection as idle and kill it. In that in mind we have additionally environment variable that will resolve that issue.

You can use in the .htaccess file “noconntimeout” variable. We will give example with SOAP API:

<IfModule Litespeed> 
RewriteEngine On
RewriteRule api.php - [E=noconntimeout:1]
</IfModule>

Variable will allow running php processes with no limits for that webpage where is the .htaccess file.

This can be very useful when you are working with modules like FarApp or Royal Mail Shipping Manager.
