There's no maximum data size imposed by HTTP. The limitation you're facing is imposed by your web-server so you'll need to increase the cap.

Another solution could be to partially build the HTML table and create a button that when pressed loads the rest (or use an EventListener to capture the page scroll position and keep loading while the user scrolls). If this approach meets your requirements, you shouldn't face any kind of data limitation.

According to <a href="https://stackoverflow.com/questions/7658193/is-there-any-size-limitation-for-ajax-post">this question</a> and <a href="https://stackoverflow.com/questions/7392694/maximum-size-of-ajax-returned-data">this question</a>, there isn't a limit to the amount of data transmitted in an AJAX request. The browser or your server could be imposing limitations. Have you tested your application with multiple browsers? Which type of server? Can you attempt to find the approximate amount of data where the request fails?

<a href="https://stackoverflow.com/questions/17810063/jquery-ajax-post-huge-string-value">This question</a> reveals there should be configuration values to allow the massive transmission. One answer proposes converting your data into a JSON string, which you have already done.

Regarding an alternative way to generate the table, my initial thought was to break the request into multiple requests (possibly based on the number of user records). Perhaps you could fall-back on this method if you can't resolve the problem. @Arnau Fernández's suggestion to load the data in small chunks as the user scrolls is similar and clever. If you don't want the scroll and load behavior you could send all of the requests at once, which would still provide the security of eliminating the massive request with smaller ones.

I see the <code>.aspx</code> in your URL. If you're using asp.net, you could try the <a href="https://stackoverflow.com/questions/5902540/increasing-maximum-response-size-from-asp-net-page-method">solution here</a>, which adjusts a value in the <code>web.config</code> file. If this doesn't help, then more information about your technologies would be helpful.

Pasting their configuration for reference:

The problem was caused by the request timeout but not the size of the data. Since I was using ajax updatepanel in aspx project I added <code>AsyncPostBackTimeOut='300000000'</code> to my 
<code>ToolkitScriptManager</code> tag and added 

<pre><code>&lt;system.web.extensions&gt;
 &lt;scripting&gt;
 &lt;webServices&gt;
 &lt;jsonSerialization maxJsonLength="300000000" /&gt;
 &lt;/webServices&gt;
 &lt;/scripting&gt;
&lt;/system.web.extensions&gt;

to my <code>Web.config</code> file as documented <a href="https://msdn.microsoft.com/en-us/library/bb513882(v=vs.90)" rel="nofollow noreferrer">here</a>. Now I can load the data without any problem though it's taking some time depending with the number of records returned. Thanks for your help.

when the json string size is big, it can't send the data to client side, so you have to increase the size like &quot;Int32.MaxValue&quot;. No need to configure web.config file.

I have the following <code>ajax</code> code which am using to get the user details from the server. Am generating the <code>html table</code> from the server side and return the structure as a string. This works fine but i get <code>undefined</code> when user records are too many. What is limitation of data that can be passed in ajax ? 
Is there an alternative i can use to generate html table in the client side ? 

<pre><code> var param = {};
 param.CompanyID = $('[id*=txtCoID]').val();
 $.ajax({
 type: 'POST',
 url: 'AjaxAsync.aspx/BindActiveUsers',
 beforeSend: function () { },
 data: '{P: ' + JSON.stringify(param) + '}',
 contentType: 'application/json; charset=utf-8',
 //processData: false,
 //timeout: 1000000,
 //async: true,
 //cache: false,
 dataType: 'json',
 success: function (rsp) {
 document.getElementById('dvUsers').innerHTML = rsp.d;
 },
 error: function (error) {
 document.getElementById('dvUsers').innerHTML = error.d;
 }
 }); 
</code></pre>
