The 414 Request-URI Too Long error generally shows up because the server is refusing to service the request because the Request-URI is longer than what server’s willing to interpret.
In Apache, you can adjust the limit of the URI length by using the LimitRequestLine directive in the Apache configuration file. The LimitRequestLine sets the limit on the allowed size of a client’s HTTP request-line. The default limit is 8190 bytes.
Here is how you can solve a 414 Request-URI Too Long error in Apache:
1. Find the Apache configuration file (httpd.conf or apache2.conf) – For Ubuntu, it is usually located at /etc/apache2/apache2.conf. – For CentOS, it is usually at /etc/httpd/conf/httpd.conf.
1. Open the file in a text editor (like nano or vim).
1. Look for LimitRequestLine directive. If it does not exist, you can add it.
1. Increase the limit in bytes, for example: `LimitRequestLine 16384`
1. Save the file and exit the text editor.
1. Finally, restart the Apache server to apply the changes. – For Ubuntu: `sudo service apache2 restart` – For CentOS: `sudo service httpd restart`
Please note that increasing the limit too much can lead to the server being vulnerable to Denial of Service (DoS) attacks. So, you need to find a balance between the need to accept longer URLs and the need to protect the server. It will depend on your specific application needs.
