I have started getting occasional errors logged from our web server.

It looks like a specific user, and possibly only some of the time.  If it happens AJAX won't work on our site (I imagine), which would make using it quite difficult .  There are maybe 200 users, who are usually on all day, but no-one has complained (yet).

This is error, logged from our default error page.  The end of the axd decoration has obviously got corrupted with some javascript.
Why does the same corrupt filename get referenced time and again ?  Has the browser cached it ?

The page you requested cannot be found.

Request RawUrl = /SeaPlanner/ScriptResource.axd?d=MZN8mrjHFHeJS_HFuw_hoFXoRri86JQ_-n6xsd10tRLAuzBPjqE1NaoSazV5LzG-X6cWyuwm-ikDSRGesWeS0t8fMPuiMKYEafpSBgnMVfaRuzktBack('ctl00$mnuMain','Log%20Off')

Referrer http://.../Seaplanner/default.aspx

UserHostAddress 81.132.73.121

UserHostName 81.132.73.121

System.Web.Extensions,

This is an invalid script resource request.,

 

   at System.Web.Handlers.ScriptResourceHandler.ProcessRequest(HttpContext context)

   at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()

   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

HTTP_USER_AGENT:Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; .NET CLR 1.1.4322; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)

The uncorrupted axd file starts thusly:
// Name:        MicrosoftAjaxWebForms.debug.js
// Assembly:    System.Web.Extensions
// Version:     3.5.0.0
// FileVersion: 3.5.30729.3644
//-----------------------------------------------------------------------
// Copyright (C) Microsoft Corporation. All rights reserved.
//-----------------------------------------------------------------------
// MicrosoftAjaxWebForms.js
// Microsoft AJAX ASP.NET WebForms Framework.

Any ideas ????

Hi Simon,

You can try troubleshooting the RadControls for ASP.NET AJAX web resources as suggested in this help topic. You can also try enabling Telerik CDN and thus the web resources will be load from the server we deployed them but from the Telerik.Web.UI dll you are using.

Best wishes,
