ErrorDocument + HTTP error can cause: Request exceeded the limit of 10 internal redirects

short description

Error: Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

When using error document and redirect/deny with fail 4xx / 5xx

example

The error document is activated for the vhost In .htaccess:

RewriteEngine On
RewriteCond %{REMOTE_ADDR} ^([0-9]{1,3})\.
RewriteCond %{DOCUMENT_ROOT}/block/%1/%{REMOTE_ADDR}.txt -f
RewriteRule . - [F,L]

correct behaviour

Should return the error document

environment

Server OS: any
Server OS version: any

ISPConfig version: all version (3.1.13)

proposed fix

When the error document is activated, it should exists a rewrite rule that lead to error document prior any processing.

                Alias /error/ "/var/www/domain.tld/web/error/"
                ErrorDocument 400 /error/400.html
                ErrorDocument 401 /error/401.html
                ErrorDocument 403 /error/403.html
                ErrorDocument 404 /error/404.html
                ErrorDocument 405 /error/405.html
                ErrorDocument 500 /error/500.html
                ErrorDocument 502 /error/502.html
                ErrorDocument 503 /error/503.html
                <IfModule mod_rewrite.c>
                  RewriteEngine on
                  RewriteRule ^/error/ - [L]
                </IfModule>
