Http error: 414 – Request URL Too Long
The 414 HTTP status code means that the request URL is too long. This can be caused by a number of things, but is most often due to a long query string being sent in the URL.
For example, if you are trying to access a website that has a lot of parameters in the URL, you may see a 414 error. This is because the server cannot process such a long URL.
414 errors are most often seen in Apache servers. If you are using Apache, you can increase the limit on the size of URLs that can be processed by changing the LimitRequestLine directive.
It is also possible to see a 414 error if you are making a POST request with a very large amount of data. In this case, you can increase the LimitRequestBody directive to allow more data to be posted.
If you are seeing 414 errors, there are a few things that you can do to try and fix the problem. First, check to see if there are any parameters in the URL that can be removed. If not, you may need to increase the limits on the server.
