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.

So I added a manifest.json to the application. I am using it to define various icon settings and mobile settings. I gave it a start url of "/", and I've tested it with a start url of "~", "." and simply leaving the property undefined.
The manifest works locally, but when I build it to a QA server I get error 500s on a bunch of javascript files in the bundle, including the VMs that generate the navigation for the app. I've added the JSON mimeMap to the web.config and have done a fair amount of research but I'm coming up blank. Help!
The ~ works with the ASP.NET rendering engine to render relative URLs. This is really limited to the server. Remember the PWA code is decoupled from your server-side code/server. The browser is only looking at the server via HTTP and is unaware of any server-side logic you may have. It only cares about what is sent to it across the wire.
Analyze your network waterfall and see what URLs are being requested. If the URLs being requested have the ~ in them, you need to change your manifest file, well you should remove that anyway IMO.
Do you know the details of the server side error(s)? Or are you masking that behind the default 5xx message in ASP.NET? It would be helpful to know what the exact error being thrown on the server is to help debug the issue.
I have deployed an ASP.NET website on IIS 7. I was able to access my site using the URL http://**local host**/sitename.aspx and all the formatting of my pages is looking good.
But when I access the same page by using the URL http://**servername**/sitename.aspx from another system or on the same server where I have been deployed, the page formatting is not working properly.
What would be the best solution for this? Thanks
First a fall to check your Js/Css file path where you have not mention static file path with localhost name.
For more detail go to browser and browse your url and press F+12 so development tool will be open and check there for broken url.
I am not sure why you are worrying about formatting soo much. I mean formatting should not affect you much unless you use <pre> in your html.
There are ways to modify the HTTP Response Using Filters. Can you please makesure none of these filters present in your application for release mode.
Generally i use HTTP compression feature of IIS to compress my content, but in browser it looks correct to me.
Here is my simple (I hope) problem:
I 'm running a web app with eclipse through tomcat 7. I use the classic servlet-model-jsp pattern. My problem is when I change something in the stylesheet (CSS) and restart tomcat and reload the page on the chrome, the new css is not loaded on the browser (I check it through the browser and i see the same as before the changes).
What is wrong and what can i do about it?!
Thank you in advance :)
I don't think this is a client issue. I think it is a bug in Eclipse/ Tomcat plugin. If you check the request.getPathTranslated() inside the servelet doGet method, it will be something like
C:\Users\YourName\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp1\
wtpwebapps\yourAppName\
So the tomcat running inside eclipse is serving up static content from there, which is different to the location of static content that you are editing, which is usually something like
C:\fullPathTo\yourAppName\src\main\webapp\static
Tomcat inside eclipse often neglects to update the static content from where you have edited it to the plugins... spot from where it serves it to your web page.
To solve the problem I use Beyond Compare or similar, and set up a compare between the directories
C:\fullPathTo\yourAppName\src\main\webapp\static
and
...\.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\yourAppName\static
If css or other static changes (such as javascript files) fail to show up in the browser, just do a quick refresh of the Beyond Compare window, this will highlight the mismatches, copy them across manually, and you are good to go.
I know this is a hack but it works for me, till the eclipse guys get this sorted out.
I am developing a flex charting web application which gets data from csv files. This application is supposed to be installed on the website of a client. The client uses a web server management system where the URLs generated are pretty long and contain non-alphanumeric characters. An example is given below:
http://www.example.com/EXTERNAL/ORGANIZATION/0,,contentMDK:20135608~pagePK:64060242~piPK:64060289~theSitePK:299948,00.html
The problem is that on my test server, the application is running just fine. But when deployed on the client's site, the application and the charts load, but the CSV data fails to load. The error given is:
Input output error: IO_ERROR
I have tried both relative referencing (relative with respect to the swf file) and absolute reference to the URL of the csv file. But both approaches have failed.
Any ideas?
I would ideally like to stay away from absolute URLs since that would break down if the charts need to move to another location.
Thanks

Umm, I don't know what to say really. Not knowing much about the server I'll have to resort to a list of things I can think of. Some of these are admittedly just a stab in the dark. In general it appears that this is a server side issue and as a front end developer you can't be expected to solve this. I know that getting the application to work is the priority here, but if you don't have access to the server there not much you can do to this issue.
First let's eliminate the completely obvious. Is the file ending definitely supposed to be .html and not .csv?
My original thought was that the CMS is somehow blocking Flash from loading the content, but would allow a browser to access it. Since it won't allow that either there are three options that come to mind:
1) The server or the browser does something to the URL when you make the request. Try installing the LiveHTTPHeaders (link) add on for Firefox, that'll allow you to look at the raw HTTP requests and responses. There might be some server side redirects that affect the request. The HTTP Headers should help you with that too.
2) The .csv files are kept in a folder that the web server doesn't have read access to.
3) maybe you need to use HTTPS instead of HTTP. This would be a bit strange since you are getting the URL from the server in the first place. The clients server admin should be able to sort this out for you.
4) I'm not sure what would happen if the script that handles your request is Python. In Python the colons are directory separators, so that might throw the whole thing off.
5) The clients management system does something strange to the URL before it's handed to you. Although I'm not sure how you would test this.
That's it I think. I'm out of ideas for now. For the testing I would forget the flex application and just try the requests from the browser address bar first. Since the application is working on your test server the issue shouldn't be your code. When you get the requests to work on the browser, if they still don't work from Flex then it's your code.
I don't know how much it helps, but there is an as3 CSVLib available.
About the IOError, can you please paste the text ?
If you listen for the IOErrorEvent and trace event.text in the handler,
you should something similar to this:
Error #2035: URL Not Found. URL: yourFile.csv

I want to go live with my site.
...but I need help with a security violation I am incurring.
I've seen various threads on this forum regarding a crossdomain.xml file to include and link to, but I don't get it... no matter what I try I still end up with the same result. You'll note below that it is not recommended to use crossdomain hacks.
FWIW, this only happens when I export a release build... I can load the php data w/out an issue in my debug/developing phase locally in Flex.
What gives? When I make a PHP based request for data I always get this error popping up:
Error #2044: Unhandled securityError:.
text=Error #2048: Security sandbox
violation:
http://alubow.com/jml_testing/viewable/alubow_project.swf
cannot load data from
http://www.alubow.com/jml_testing/foldergrab.php?ipath=assets/bitmap/portrait_thumbs/&tpath=assets/bitmap/portrait_imgs/.
at utils.php::DirectoryReader() at
alubow_project/newScroller() at
alubow_project/mainClickOut()
Is there code I need to add to get this to work? Do I need to configure the server I am using?
I will need to go live with this site soon and these errors I am getting both locally and serverside (via a browser) are unacceptable.
COULD THIS BE A PROBLEM WITH THE FLASH PLAYER I HAVE INSTALLED?
I have the debugger version of flash player 10.

The problem is with the www prefix. I guess you are trying to load a page with out the www subdomain and the URL you are looking for does have that prefix.
Now, what you need to do is one of the following:
change the request url
add both www.yourdomain.com And yourdomain.com to the crossdomain.xml
call the url dymanicaly. this is the best solution but needs some more work. you can get it done using ExternalInterface and connection to JS here. OR you can use the BrowserManager.
Enjoy!
It may be because your app is requesting from www.alubow.com when hosted from alubow.com, which triggers a request for http://www.alubow.com/crossdomain.xml, which doesn't exist. You could refer to your app as www.alubow.com/jml_testing/viewable/alubow_project.swf and avoid the error.
Alternately, you could add a crossdomain.xml file to www.alubow.com.
I know this is weird but for local files loaded through the flash player you probably just need to hit this page. Look near the top right for something that looks like an example image. It's actually a Flex application. Click successive tabs until you read the Global Security Settings panel (currently 3rd from the left, with an image of a globe and padlock). Select the "Edit locations" menu, and choose "Add location". You can then add your swf or your folder of swf's into the whitelist and they'll be able to access outside resources magically.
