Hi,
The Apache log files are (almost) entirely filled with lines like the one below, and they fill up very quickly.
| Code: | [Thu Aug 06 14:32:56.147608 2026] [proxy_fcgi:error] [pid 7240:tid 140597490640640] [client 20.52.171.102:33522] AH01071: Got error 'Primary script unknown'
[Thu Aug 06 14:32:56.213311 2026] [proxy_fcgi:error] [pid 7240:tid 140597616531200] [client 20.52.171.102:33522] AH01071: Got error 'Primary script unknown'
[Thu Aug 06 14:32:56.253052 2026] [proxy_fcgi:error] [pid 7240:tid 140597952239360] [client 20.52.171.102:33522] AH01071: Got error 'Primary script unknown'

My web host told me that this was caused by a bot and that it would be a good idea to add the following lines to an .htaccess file:
| Code: | <IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} ^\s*$ [OR]
RewriteCond %{HTTP_USER_AGENT} "(?:Amazonbot|BLEXBot|Barkrowler|DataForSeoBot|MJ12bot|DotBot|AhrefsBot|SemrushBot|SeekportBot|CCBot|Baiduspider|Yandex|Sogou|PetalBot|Bytespider|OAI-SearchBot|GPTBot|ChatGPT-User|PerplexityBot|ClaudeBot)" [NC]
RewriteRule ^ - [R=429,L]
</IfModule> |
What do you think? |

It is a better solution to get a real 404 error. To do that you better check if that file exists.
| Code: |
<Files ~ "\.php$">
<If "-f %{REQUEST_FILENAME}">
SetHandler "proxy:fcgi://127.0.0.1:9000"
</If>
</Files>

Thank you.
However, if I add this to the .htaccess file on my local site, when I request access to the website, a window appears with the title:
Enter the file name for saving
And a file name like: IRbiKAYR |

| Pardon me for that. How was the Handler set before? Because now the file content is sent as a download. I'm pretty sure it contains the PHP code. |

Hi,
The Handler is :
| Code: | | AddHandler application/x-httpd-php .php |
And, yes the saved file contains the PHP code. |
