I have to send the XML from the client side to the server side.

The method adopted by me was that:

First the xml is converted to string in the javascript and then post as a uri

var url = '/perl/set_zorder_xml.cgi'+'?'+xmlString+'&'+location+'&'+'nocache='+randomnumber;

xml string is the string that contains the xml in string form.

The post function looks like this:

if (window.XMLHttpRequest) {
            req_anno = new XMLHttpRequest();
            req_anno.open("POST", url, false);
            req_anno.send();
            }

The problem is that when my xml string is very large then html 414 error occurs i.e url too large. Is there any way out, Javascript and perl is used

• javascript
• string
• post
• xmlhttprequest

• Wouldn't you normally send() the XML, and not add it to the querystring, seems like a strange thing to do, as you're making a GET request with a POST request. – adeneo Commented Jul 17, 2013 at 11:23

• if you use jquery, you may launch the request as a genuine POST request with the ajax methods. this basically sends content together with the url. this content corresponds to the url-parameters and their values and doesn't fall under the url length limits. – collapsar Commented Jul 17, 2013 at 11:28

Even though you're doing a POST request, you're still sending the data in the querystring of the URL. Instead you should move the data to be sent as POST data, and remove it from the URL.

req_anno.open("POST", '/perl/set_zorder_xml.cgi', false);
req_anno.send('xml=' + encodeURIComponent(xmlString));

The XHR .send() method accepts the string to be sent as the request body (ie POST data).
