Request-URI Too Large [duplicate]

Question

This question already has answers here:

How do I resolve a HTTP 414 “Request URI too long” error? (5 answers)

Closed 7 years ago.

Got this error on a big $_GET query in size ~9 000 symbols (they are divided into ~10 variables).

Request-URI Too Large

The requested URL's length exceeds the capacity limit for this server.

What is a workaround for this problem?

Answer 1

There is no workaround if you want pass all these info with GET without change server configuration.

Other solutions:

• Use POST with a form (or an hidden form and add onclick event at your link that submit it)
• Use Session. When the server generates the link, store it in $_SESSION with an unique id (or RID, it can be md5 of complete URI) and pass it via GET.
• Use Database or file storage (with the same procedure of session)

Answer 2

This worked for me (it needs formData support):

<script>
  //Load form
  var formData = new FormData();
  formData.append("param_name1", "param_content1");
  formData.append("param_name2", "param_content2"); 
  formData.append("param_nameN", "param_contentN"); 

  //Send form via AJAX
  var xhr = new XMLHttpRequest();
  xhr.open("POST", YOUR_URL);  
  xhr.send(formData);
</script>

Answer 3

Well an URI actually have a character limit depending on several things. You can check it out at

One workaround is to use POST instead of GET if you are the one developing the server too.
