'Sys' is undefined - revisited

[David]

Sorry, I accidentally placed this post in the wrong area before this. Feel free to remove my other post... It's one of those days...

--- Post starts here ---

I know, there's like twenty of these threads already, but I'm losing my mind and I'm about to put my keyboard through my monitor... I've built a small application using Telerik's menu, gridview, and the ASP AJAX Controls MediaPlayer control. Everything worked fine with it until I tried to put it onto the server. It played fine locally (until I had to modify the config), and it still plays fine on the intranet where I developed this. I am getting these two errors:

'Sys' is undefined
'Telerik' is undefined

I have attached my web.config file. I can't find anything. Probably because I'm new to ASP.NET development (but not to programming). If you can find anything that might fix this, please, help me... This is so discouraging as the program is ready for launch as version 1...

I'm really irritated. Sorry...

Hello David,

Receiving those errors means that you have some problem with web resource registration. Please check this blog post for troubleshooting instructions.

All the best,
Albert

[David]

I have checked this blog and everything seems to be correct. I even downloaded Fiddler, and I am getting a 404 error on this call:

/tv/Telerik.Web.UI.WebResource.axd

However, I have the httphandlers set up as so:

<add

verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false" />

 

<add

path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Version=2008.3.1314.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" verb="*" validate="false" />

 

I have checked IIS and everything seems to be configured correctly.

I am running this application on both the intranet and on the internet. It works PERFECTLY on the intranet. It breaks on the intranet. Two different servers. I am going around in circles, wasting so much time. I have checked and double-checked and triple-checked everything in this blog entry and other links all over google, but nothing works...

Stupidest thing in the world because the application is built and it runs perfectly on the intranet...

Here is the web.config one more time if you care to take a look. PLEASE don't just post another link. I've googled the hell out of this for three days now...

On second thought...

I'm thinking this is something on the server side. I can't think of any other explanation. IDENTICAL CODE runs perfectly on the intranet server but fails on the internet server. Both have .axd set up with "verify file exists" unchecked. Is there anything else that could cause the Telerik.Web.UI.WebResource.axd to return a 404 page not found? Why would it work on one server and not the other?

[David]

Ok, I think I found the problem. It's nothing you could have found, and it was server-side as I thought...

Rejected-By-Urlscan

The problem is that the Telerik.Web.UI.WebResource.axd is being rejected by Urlscan.

I will talk to the networking people and hopefully fixing this will fix the problem.

I hope this post will save someone a few hours...

Hello David,

[David]

No problem, Paul. I love the controls.

Urlscan blocked Telerik.Web.UI.Webresource.axd because there was a script embedded into the query string. It might be a good idea for Telerik to write some documentation about this as this was quite the pain to figure out... Now I know to check the web logs sooner rather than later. I cut and cut and cut away at my code but nothing would get fixed. If I had just checked the server logs and then the Urlscan logs, I could have figured this out in minutes...

I think I only saw one other person even mention urlscan with regards to Webresource, so it might be worth documenting. :) Hopefully, my anguish saves someone else time.
