Definition: The "htaccess.txt" in PHP stands for HTHPR, a text file that defines various settings on web servers. It's used to restrict certain HTTP requests and methods.
Here’s a basic example:
```
HeaderSet('Access-Control-Allow-Origin', '
');
HeaderSet('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE');
HeaderSet('Access-Control-Allow-Headers', 'Content-Type, Authorization');
# Set Content-Encoding header to deflate for compressed responses.
HTTP/1.1
Vary: Accept-Encoding
```
This text file serves as a rule set within the PHP framework to block requests from certain domains and methods, providing additional security measures against common attacks like denial-of-service (DoS) attacks.
It's a vital component in securing websites and applications by controlling which HTTP headers can be sent along with data. It’s often used alongside other security tools or scripts for specific domain restrictions.
