Apache 2.4.41 checking env variable value

["Salim Abdul -X (salimabd - HCL TECHNOLOGIES LIMITED at Cisco)" <salimabd@xxxxxxxxxxxxxxxxxxxxx>]

Hi Experts,

 

I want to check the value of an environment variable which is already set.

 

<Directory />

    AllowOverride None

    Require env XYZ == ‘SUCCESS’ || expr “%{REQUEST_URI} == ‘/xyz/register/register.rq’"

</Directory>

 

Here I want to check the variable is ‘SUCCESS’. What is the correct syntax to check the value of the env variable.

 

Thanks in advance,

 

Regards,

Salim
