In my site, I had a button that will trigger a Ajax post to my server. When my data is with the content-length "32109", the post will rejected with a empty body response with xhr.statusText "error". If my content-length is "27549", i'm able to post successfully to my server.

Tested the same scenario in IE and Chrome and both working fine with content-length "32109".

Code:


$.ajax({

           url: "update",
           dataType: "json",
           data: {
               parameter_data: JSON.stringify({
                   meta_datas: metaDataObj,
                   attributesValues: this.data
               })
           },
           type: "POST",
           success: function(data) {
               ...
           },
           error: function (xhr, desc, err) {
               ...
           }
       });


Request headers:


User-Agent:"Mozilla/5.0 (Windows NT 6.1; WOW64; rv:39.0) Gecko/20100101 Firefox/39.0" Accept:"application/json, text/javascript, */*; q=0.01" Accept-Language:"en,zh;q=0.8,sq;q=0.6,zh-TW;q=0.4,en-US;q=0.2" Accept-Encoding:"gzip, deflate" Content-Type:"application/x-www-form-urlencoded; charset=UTF-8" X-Requested-With:"XMLHttpRequest" Content-Length:"32109" Connection:"keep-alive" Pragma:"no-cache" Cache-Control:"no-cache"

The response body is empty.

xhr:

- state = rejected
- statusText = error

May i know why the request is rejected? Note: The request never reach the server
