I have my app that is creating an XML File with XMLTextWriter class in ASP .Net C#. I create a nicely formed xml file, then spit out a link for the user. When I click on the link, I recieve an error saying that Page cannot be displayed:
"HTTP Error 405 - The HTTP verb used to access this page is not allowed."
However, at this point I place my cursor in the adress bar of the browser, and hit enter and Viola!, my nice xml file is displayed.
Why does it take an enter, in order to make my browser behave.
What can I do to to correct this so that when we click on the link the xml file displays without needing the extra enter in the browser address bar?
I went into my web server already and added the XML mime type to the registered mim types at the web server level.
I am wondering what could be the problem?
From the error message it seems there is something wrong with the link you are using.
View the source from your browser and verify that the tag is pointing to the correct location. Also, make sure it is only pointing to the one document and not doing anything else like calling javascript functions or posting back.

I have developed a website which contains a few pages, for example:
http://localhost:32080/PlanSummary.aspx
However, when I type /djwfjafjd or any random character or string after the aspx page, I can still access the website normally without any 404 error. (Browser still displays PlanSummary.aspx page) But it should display an error like 404 that this page does not exist.
http://localhost:32080/PlanSummary.aspx/djwfjafjd
At this point, if I click on other link on the page, for example, ProductionPlan.aspx it will navigate to http://localhost:32080/PlanSummary.aspx/ProductionPlan.aspx but browser still displays PlanSummary.aspx page.
I earlier believed that this has something to do with error handling, which I currently using httpErrors to handle 404 and 500 errors and it works perfectly. I tested it by accessing http://localhost:32080/PlanSummaryxxxxxx.aspx and it redirected me to "friendly" not found website that I created.
Right now I really don't know what is the cause of this problem. Please let me know if I need to provide more information.
Hi guys this is my follow up question and I think this is the real issue here. Click Here
Whenever I access the file using the directory browsing (eg. http://localhost/temp/1.pdf) it always render the old or previous PDF file even if I change the entire file with the same file name, example I have 1.pdf with some content then I delete this file on the directory then replace with new and different content and rename it to 1.pdf then when I access it using browser it always render the previous value not the new one that I replace. This only happens on IE and Opera browser. Please need help this is a production issue.
Edit:
I found something very strange, example i have this url for the location of the pdf file (eg. http://localhost/website/tempfolder/1.pdf) the first pdf that I generated will show then some part in my code I change the casing of some letter example 't', I change it to 'T' then the newly pdf shows but when I revert back to the old case expecting that it will show the new pdf but sad to say the first PDF file shows.
Your browser is probably caching the PDF files.
For IE, you can do a CTRL F5 to force it to reload from web server.
Or put a random query string in your URL
e.g. /temp/1.pdf?v=1, /temp/1.pdf?v=2
Assuming you server is IIS, permanent solution is to configure HTTP response headers.
Go to IIS manager
Navigate to your folder
Click "HTTP Response Headers" in Features View
Right-button click/select "Set Common Headers"
Check "Expire Web Content" and select "Immediately".
Two aspx pages are involved with the problem. in one form I am collecting the entity and binding it in a session variable and then with button clicked, I am trying to get to the other aspx page with response.redirect("") method. But, the problem is its gives me an error message with a strange URl.
let me show you the code I have writen
formSaleMoneyReceiptEntity = ViewFormSaleMoneyReceipt_DAO.GetMoneyReceiptByFormSL(formSl);
Session["MoneyReceipt"] = formSaleMoneyReceiptEntity;
Response.Redirect("~/Reports/MoneyRepeiptFormReport.aspx",false);
I am using local host and the URl I am getting is that
http://www.google-feed.net/results.php?q=localhost 5808 StudentManagement FormSaleMoneyReceipt aspx &cx=002904446094441487865%3Ate-nlsbrcdy&cof=FORID%3A10&ie=UTF-8&said=&do=search&empty=0&from=2&CID=1
why is this so? I don't have any idea. Please help me out.
It looks like the URL that is passed to the browser doesn't exist, so you're getting a redirect to a Google search page instead.
Is it ~/Reports/MoneyReceiptFormReport.aspx by any chance?
A good tool to use to debug this kind of situation is Fiddler. This sits as a proxy between your Web server and your browser and issues a trace of what requests and responses are made. Browsers have a habit of reformatting error messages, Fiddler will show you exactly what's sent to the server and what comes back.
I have a question about outputting PDF files. Currently I'm storing the PDF in the database in binary form. I'm outputting the PDF file via a URL such as:
http://myhost.com/FileManager.aspx?FileId=8465b2f9-b64e-4a9a-a449-94b5adb3b278
so from what I could deduce, to the browser this is an .aspx page that is loading and not a PDF. Firefox and IE interpret this correctly and launch Adobe Acrobat, however since Chrome (12.0.742.112) has its own implementation of a PDF reader, it will open the file correctly, but then when someone goes to save the file in chrome, it wants to save it as a .aspx. If I simply rename the .aspx to .pdf, the file downloads correctly. However, I"m trying to avoid telling my customer that s/he may have to take that extra step.
When I chose to look at the headers that loaded in Chrome via Web Inspector, I see this:
FileManager.aspx:-1 Resource interpreted as Document but transferred
with MIME type application/pdf
I can completely understand why Chrome would say this.
Furthermore, I get a save as box upon page load when I add:
Response.AddHeader("content-disposition", "attachment;filename=blah.pdf");
However, I was hoping to just keep the file in a browser. So aside from using some URL Rewrite, is there a way I can manipulate the HTTP Headers to simply open the page as a PDF and save correctly in Chrome?
Lastly, I tried using a WebService, but I can't seem to write the binary data to the page.
this.Context.Response.BinaryWrite(bytes);
Any help is appreciated!
In the web application's top-level web.config, add the following <add> element to the <httpHandlers> section:
<httpHandlers>
<add verb="*" path="FileManager.pdf" type="ProjectName.FileManager" />
...where ProjectName.FileManager is the full name (namespace and classname) of the FileManager class in FileManager.aspx.cs.
This tells ASP.NET to handle the path /FileManager.pdf using the handler defined by ProjectName.FileManager. (System.Web.UI.Page implements the IHttpHandler interface, so every webform is a handler.)
Now you can serve the PDFs via a URL with a .pdf extension like so:
http://myhost.com/FileManager.pdf?FileId=8465b2f9-b64e-4a9a-a449-94b5adb3b278
You do not need to rename the physical FileManager.aspx file. When the user enters /FileManager.pdf?FileId=foo in the browser, ASP.NET will handle the request with the ProjectName.FileManager class defined in FileManager.aspx.
Note:
The above should work on Cassini (the Visual Studio "mini" webserver) with no further changes. However IIS by default only sends *.aspx, *.asmx, *.ashx requests to ASP.NET. Therefore, for the above to work on IIS, you need to tell it to send requests for /FileManager.pdf to ASP.NET. That is, you need to configure a "mapping".
With IIS 6 you need to configure the mapping using IIS manager.
With IIS 7 you can configure a mapping from your web.config--this makes deployment easier, but it depends on how your hosting is set up.
Something that worked for me was to add the intended filename between the application page name (in your case, FileManager.aspx) and the query mark (the ? mark).
So, in the end, you'd have something like this:
http://myhost.com/FileManager.aspx/myfile.pdf?FileId=8465b2f9-b64e-4a9a-a449-94b5adb3b278
Surprisingly, the correct application will run (Filemanager.aspx), the variables will be passed unharmed (FileId), the result will be treated as inline (if you didn't change it to attachment, that is) but the browser will think that the filename to use, in case the user wants to save the page, is myfile.pdf.
I have Flex application requiring to filter users depending on there database groups. Depending on which group they are, the're is a config.xml file that is use to populate the swf.
Here is how I figure how to do this :
1. The client comes to a .aspx page with a form requiring a username and a password.
2. On the server side I confirm the user credential
3. Once the username/password is valid I redirect to the mxml file with the config.xml file in the html headers (post).
My problem comes when I need to get the post data from the http request. Let's say I have this code :
<mx:Application initialize="init()">
<mx:Script>
<![CDATA[
private function init():void
{
// get the post data here
}
/* More code here */
]]>
</mx:Script>
</mx:Application>
How do I get the post data on the init() function.
Thank you.
For those that would be interested, I've found some ressources on the Adobe Flex 3 Ressource center.
Basically there is no current way to pass data with the POST method. You can either add the parameters at the end of you swf url (GET method) as shown here : http://livedocs.adobe.com/flex/3/html/help.html?content=deep_linking_5.html#245869
The other way is to embed them in the page with the flashVars method shown here : http://livedocs.adobe.com/flex/3/html/help.html?content=passingarguments_3.html#229997
If you still wonder, how I'll manage to do this if you run to in the same situation. Here is my idea (feel free to share if you have different vision) :
1.User logs in login.aspx
2.Depending on the credentials of the users the server side code modify the index.html file to embed the correct xml file in the flash object.
3.With the FlashVars method, I get back the xml file path and job done!
If you ever run in a similar situation and need help contact me.
I don't think it's possible to get the POST data, but others might have a way. An alternative solution would be:
User logs in: login.aspx
User directed to Flash content: content.html embedding content.swf
Flash requests config.xml from server: content.swf makes HTTP request for config.xml.aspx
Server provides user's configuration in config.xml.aspx
In your init() function, you'd make the URLLoader request to get the configuration, and you'd do the configuration in the Event.COMPLETE handler.
Another possibility is to use HTTP cookies--not handled natively by Flash, but you can get to them via Javascript--see this CookieUtil class.
