MS Chart not showing on hosted site - asp.net

I have a MS Chart component displaying fine on an ASP.Net page. When I deploy it I get a broken image. The settings in the web.config are the same and the temporary images folder has the correct permissions.
When I get the URL of the images I can see that the /.png file is not getting created.
What sort of things do I need to look at to track down the problem?

I was able to resolve the issue by ensuring that my application pool settings was using "ASP .net integrated" and not "ASP .Net Classic". This will ensure that your handler is being used.

I had the same problem when I was working with the charting in .NET 4 and my problem turned out to be related to the default value of the privateImages attribute and the fact that my code wasn't using any identifying attributes for the session or the user.
See my post here for an explanation of how I solved my problem.
It's also worth noting that the ASP.NET Development server ignores the config settings for charting and renders them in memory unless you specifically set an attribute to force it to use your config.

Problem with Default Document and IIS7.5/Windows 7

I'm having a problem with a component used in a Sitecore solution on our Windows 7 workstations that is driving me batty.
In short, the component in question adds <script> tags to the page that load supporting JavaScript files. The src attributes are set to something like:
/path/to/scriptgenerator/?r=1234&p=asdf
Those paths are not working - I'm getting a 404 back.
You might thing "oh ... well, the path doesn't exist." But it does, and it also has a Default.aspx page in it. In fact, if I try the following path, the JS is generated and returned by the server:
/path/to/scriptgenerator/Default.aspx?r=1234&p=asdf
We're testing the site using IIS7.5, not Visual Studio's debugging web server. Of course, on the production machines, which are Win Server 2008, things work just fine.
The component in question is a third-party component and I have no access to the source code, so I can't just modify it to append default.aspx to the SRC path.
I have checked to verify that Default.aspx is set up as a default document for the site, and it is.
I tried to work around the problem using ISAPI_Rewrite, but for some reason, rules that I set up for /path/to/scriptgenerator are ignored.
I've tried the solution described in these questions, and that has no effect on my problem:
IIS 7 Not Serving Default Document
ASP.NET 2.0 and 4.0 seem to treat the root url differently in Forms Authentication
I'm really not sure what to try or look for next ... any suggestions?
Is this component set up within the same IIS Site as the Sitecore application?
If so, have you added path /path/to/scriptgenerator to IgnoreUrlPrefixes setting in web.config?

Web.Routing for the site root or homepage

I am doing some work with Web.Routing, using it to have friendly urls and nice Rest like interfaces to a site that is essentially rendered by a single IHttpHandler. There are no webforms, the handler generates all the html/json and writes it as part of process request.
This works well for things like /Sites/Accounting for example, but I can't get it to work for the site root, i.e. '/'.
I have tried registering a route with an empty string, with 'default.aspx' (which is the empty aspx file I keep in my root folder to play nice with cassini and iis). I set RouteExistingFiles to false explicitly, but whatever I do when hitting the root url it still opens default.axpx, which has no code it inherits from, and contains a simple h1 tag to show that I've hit it.
I don't want to change the default file to redirect to a desired route, I just want the equivalent of a 'default' route that is applied when no other routes are found, similar to MVC.
For reference, the previous version of the site didn't use Web.Routing, but had a handler referenced in the web.config that was perfectly capable of intercepting requests for the root or default.aspx.
Specs: ASP.NET 3.5sp1, C#, no webforms, MVC or openrasta. Plain old IHttpHandlers.
Fixed my own problem: the issue is the integrated web server, Cassini or some such. Seems that it doesnt play nice with routing, and will by default simply return the default.aspx file or, if it is missing, show a directory listing.
Using IIS with a virtual directory works fine, but is annoying (frustrates code sharers because they need to set up new virtual directories when they open my app, and pollutes my own IIS instance. Bah. Probably what I'll do for the moment however, or setup a new application manually so I can use the domain host only path like what will exist in live.
An alternative is to use the updated version of cassini, seen here, which works if the default.aspx file is missing, but I have not worked out how to integrate it with visual studio yet. Any help would be appreciated, but its not a big priority given I have workarounds.
I realise that this is a really old post, but I just ran into the same problem using VS2012, so I'm posting this here just in case.
I solved the problem by installing IIS Express and setting the project to use IIS Express in Visual Studio. Solved the problem.

newbie question about css property set up in Web developer 2010 Express

I am relatively new in C# and ASP.NET MVC.
There is something unusual that happens and it could be a simple property setup...
I have a MVC Web app and a css file associated with it in my Content folder.
Now everytime I do some changes in the css file I don't see these changes when I run the app. It seems that whatever I do the app keeps on using the old file. I can see it when I do a View Source on the page.
I played a bit with the Copy to Output Directory property in Web Developer without any good results.
Am I really missing something here ?
Thanks
Either restart casini, the web server for asp.net, the icon down by the clock or try hitting F5 in the browser a bunch of times.
Try clearing the cache in your browser.

No styles / images on asp.Net MVC 2 application

Greetings
i have a little problem with my ASP MVC application.
On my local development server everything works just fine but when i try to publish the application to an IIS 7.0 server it just displays plain pages without any styles / markups / images.
I put all those things in the /Content/ subfolder but when i try to access that folder on the production server it just returns me a 404 not found error.
I set the IIS server up with .Net 4.0 and followed the deployment guide on here: http://www.asp.net/learn/mvc/tutorial-08-cs.aspx
All views / controllers / classes seem to work just fine, the only thing which does not is the content subfolder and i cant see why.
Anyone got a suggestion what i could have overlooked or does anyone know that problem?
I had the same issue, but I found the reason why it was forcing authentication on the Contents folder.
When a user is not logged in yet, they are classified as Anonymous Authentication. In IIS7 (which is what I am using, guessing it is the same in IIS6) you need to open the authentication window in features view. Then edit the Anonymous Authentication, to use your application pool identity, or the default one, just make sure that user has permissions to read in that folder.
That fixed it for me, hope it works for you.
Well, I added the IIS_IUSRs to the project directory and found the same problem:
CSS won't load and nothing from the content folder.
But it resolved the Unable to start debugging on the web server problem.
Then, I added the IUSR to the same folder and that fixed the problem. Now, I can see images, css styles and all that stuff.
This is because you are probably using a fixed path on the src, like: ../../Content/Styles/style.css. In MVC you should use the Url helper: Url.Content("~/Content/Styles/style.css").
Using the Url helper you should have no issues.
Been pulling my hair out all night with this one.
On W2K8, MVC2, .NET 4.0, and IIS 7 (using VS 2010)
Made sure that IIS_IUSRS had full rights to the root folder but still no go - css, js, images still not being accessed in rendering the page....
and then .... so simple:
In Features view for the site - defined MIME types for .js, .css, and .jpg - and voila!
Sweet!
p.s. my 1st mvc app - and I think I'm liking it...
Check the properties of your content folders...see if they are not 'copying locally' for some reason.
The folder that your virtual directory is pointing to gave to the user "All" reading properties.

Using HttpModule to Display Images

I have an HttpModule that displays images that follow a certain URL pattern. For example, /images/employees/jason.jpg is handled by the module, but all other images aren't. It works just fine on my local machine (Cassini and IIS 7). However, the IIS6 production server isn't working. I've had the hosting company map the images to the ASP.NET worker process. Now, all images are showing that they can't render except for the images that should be rendered by the module. They are working correct.
I ran an HttpWatch instance on one of the files and received the following error:
ERROR_HTTP_INVALID_SERVER_RESPONSE
Any ideas?
Final Answer:
The module needed to be updated to transmit server files. So, I added an else to my original if and checked to see if it was an image type (by using a utility method) then use Response.TransmitFile() to pass on the file to the browser.
I then ran into a spacing issue with the images. This was because I forgot that I had .aspx files registered as an image type to perform the testing. So each page would crash during the debug process or add padding that was established from CSS. Doh!
Everything is just peachy now. Thanks to all!
There's doesn't seem to be anything particularly wrong with your module, so the issue must be coming from somewhere else. Have you got security that might be blocking the images? What actually gets returned when you request a static file?
I'd suggest seeing what gets returned (and its headers) using something like firebug to check things like the response code, content type, the actual raw response, etc...
check your web.config IIS6 / IIS7 have different places to add modules and depends on what mode your IIS7 is running in.
