How to / Re: [Solution] Nginx + Varnish + Apache force SSL .htaccess Redirect Loops

« on: October 13, 2021, 06:01:31 PM »

Hello,

I know this issue, and i cant fix not yet but you can use temporary fix :

If you using only Apache, you can use this code for HTTPS redirecting in .htaccess file :

# Before evereything, redirect HTTPS
<IfModule mod_rewrite.c>
   RewriteEngine on
   RewriteCond %{HTTPS} !=on
   RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

   RewriteCond %{HTTP_HOST} !^www\.
   RewriteRule ^(.*)$ https://www.%{HTTP_HOST}/$1 [R=301,L,E=HTTPS:1]
</IfModule>

If you using NGINX + APACHE with reverse proxy etc. you can use this code for HTTPS redirecting in .htaccess file :

# NGINX + APACHE Before evereything, redirect HTTPS
<IfModule mod_rewrite.c>
   RewriteEngine on
   RewriteCond %{SERVER_PORT} 80
   RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

   # If you want www redirect..
   RewriteCond %{HTTP_HOST} !^www\.
   RewriteRule ^(.*)$ https://www.%{HTTP_HOST}/$1 [R=301,L,E=HTTPS:1]
</IfModule>

High Performance / Re: Is reseller panel available on CWP pro

« on: July 28, 2019, 11:13:16 PM »

Hello there,

Centos Web Panel's infrastructure and itself are more powerful than most web panel systems on the market.

When the Reseller system comes to CWP, I will write an advanced module for WHMCS and make it open source for everyone at the Forum.

In addition, when the Reseller system comes to CWP, I will move all accounts and systems in cPanel to the Centos Web Panel system through CWP PRO.

In short we all expect this property.
Thank you to everyone who has worked for Centos Web Panel.

Regards.

Congratulations now your server own best ddos protection system L7 GET POST Attacks,HTTP FLOOD Attacks,L4 TCP Floods,SYN Spoofing,IP Spoofing.

Only UDP does not prevent flood attacks, your dns server.

Delete or close the port 53 from the CSF.

You will get protection against udp attacks using companies like yandex and google for free dns hosting service.

Regards. (i hope it works)
