Topic: mod_rewrite: How to define a variable and use it in rules?

[jack01]

Hi,
I am writing a rewrite rules using mod_rewrite module. I have the same data repeating all over the rules that I would like to replace with variable and set variable once at the top of rules then use variable in the rest of rules. Then if I need to add another IP address I would just add additional IP address to the variable instead like now need to change several rules.

For example I have IP addresses that I would like to set as a variable.

Now rules are the following (simplified) in httpd.conf:
**************************************************
RewriteEngine Off
RewriteCond %{REMOTE_ADDR} (192\.168\.5\.20|192\.168\.7\.15|10\.10\.20\.50)
RewriteRule (.*) - [R=404,L]

<many other conditions/rules with the same IP addresses>
**************************************************

Is there a way that I can set a variable like something:
**************************************************
RewriteEngine Off
SET_VARIABLE block_IP_addressees="192\.168\.5\.20|192\.168\.7\.15|10\.10\.20\.50"
RewriteCond %{REMOTE_ADDR} (block_IP_addresses)
RewriteRule (.*) - [R=404,L]

<many other conditions/rules with the same IP addresses>
**************************************************

My software:
- Apache httpd 2.4.27 from Apache Lounge installed on Windows 2008 R2 on Intel server

Thanks
