This Website Requires You To Log In Sharepoint 2013
were being presented with 403 ‘forbidden’ errors when trying to load our intranet site. After refreshing the screen four (4) times, the sharepoint 403 "this website requires you to log in" page would finally load. I checked the web server’s Application log and found that every time a user received a 403 error, there was an “Information” Web Event message logged with a source of ASP.NET and an ID of ID 1314. The body of the event included, among other information: Event code: 4011 Event message: An unhandled access exception has occurred. %d bloggers like this:

How can I log the reason for it? The foo.js client: function postAjax(url, queryString, callback) { var x = new XMLHttpRequest(); x.onreadystatechange = function() { if (x.readyState === 4) { // 4=after HTTP response content finished loading if (x.status === 200) callback(true, x.responseText); else callback(false, x.status); } }; x.open('POST', url, true); x.setRequestHeader('X-Requested-With', 'XMLHttpRequest'); x.setRequestHeader('Content-type','application/x-www-form-urlencoded'); x.send(queryString); } var params = 'aaa=xxx&bbb=yyy'; postAjax('bar.php', params, myCallback); function myCallback(ajaxStatus, ajaxResponse) { /* do something */ } The bar.php server: New info appended: Browser Console (in this example Firefox): When all is good (most of the time): + POST http://example.com/bar.php 200 OK ZZZms When error (e.g., after the 7th time the last I tried): + POST http://example.com/bar.php 403 Forbidden X ZZZms and I get back 403 in ajaxResponse, which comes from x.status Expanding the '+' in the Firefox console, I see the response:
