Changing Response Type In Aspx Page Breaks In IIS7?
Mar 3, 2010
I have a custom implementation of Application_PreRequestHandlerExecute which is applying a deflate/gzip filter to the response. However, on IIS7, this is failing on my "script generator" pages. These aspx pages take in Query String values and return a custom bit of script, changing the response type to text/javascript. I think it is failing because of the way iis7 uses mime types, but I'm unsure how to fix it short of turning all compressio off.
I'm trying to write a simple website (ASP.NET v4), which will call Windows Search, find a specific file and return it to the user. I've put together the following as an example: it calls the Windows Search service on "remoteserver", and returns the path of "somefile.txt":
There are cases where I have to change this query dynamically at runtime, so I do the following:
SqlDataSource1.SelectCommand = sql; // 'sql' is the new query GridView1.PageIndex = 0; GridView1.EditIndex = -1; GridView1.SelectedIndex = -1; GridView1.DataBind(); updatePanel.Update();
This works just fine actually, but when I click the pagination controls, the result set defaults back to the SelectCommand defined in the SqlDataSource1.
what i have is the follwoing Page1.aspx.cs has the following redirection in it. Response.redirect(Errors.aspx) once i go to the errors.aspx page i have a back button but at the moment it does a history.back(-1) . That is not totally corect, what i want to do is when i click on the back button go to the page that originated the call ie Page1.aspx so it goes through the Page_Load in order to refresh statues on the page. What is the best way of achieving this?
I am working in coordination with the pHp developer, he is sending me some username, key at my aspx page and on that basis i am checking the authenticity from the DB, if authentic user then i'll do response.write("YES"), if not then i'll do response.write("NO"). The PHP developer saying that he will read my response.write and on that basis he will allow the user to get logged in to his PHP site. i want to know how will he read My response.write from ASPX page. He was saying he will read it, and will put it in session, i am very confused how will he read my response.write.
I'm trying to use the Response.Write() method to dynamically insert content in the < head > section of an aspx page. I need to inject a string value from a property on a code-behind object which is a link to my CSS file. However, it is not being processed properly at run time. The object is public on the class and is hydrated in the Page_Load() event. Down in the body of the page I can successfully inject other properties from the Corpoartion object with no problem at all.Why does this not work in the < head > section?This is the part that does not expand correctly:
I have an webforms app that loses it's session variables on response.redirect. I've read Bertrand Le Roy's blog about this and still can't get it to work. The page works in production. However, when I try in the VS2k8 IDE, the session variables are there right before response.redirect and on the first line of the next page, the variables are nothing. I've confirmed the session id is the same so I'm not skipping sessions. The target page is relative so the web server doesn't think we're changing sites (as confirmed by the sessionid).
I've run into a strange problem regarding default buttons in master pages and IIS7 rewrite module. All my content pages have default buttons set in the code-behind (on prerender), or they are in panels on the aspx page. This works fine on my local machine and on the production server. However, when I enable IIS7 URL Rewrite, the default button is always to the one in the master page.
I wrote a small .NET applications that removes all line breaks in aspx/html/css code to make it harder to read for people trying to steal my design. And surprisingly I get weird characters that appear out of nowhere such as Â, » and others. They all stay at the same places, but I have no clue why they appear.
I have tried to replace Response.AddHeader with Response.AppendHeader, however the result is still the same. Also, I have tried to replace the Response.ContentType with application/octet-stream and image/jpeg, I also faced the same result.
Is there any setting/modification on server/code that I need to look on?
<MyUserControl id="myusercontrol" runat="server" MyUrlProperty="http://myurl.com/" /> which can't be casted from System.String to System.Uri EDIT The control is a sealed class and I don't want to modify it or write an own control. The goal is to set the url-property which is of the type System.Uri and not System.String.
I am using a script manager for ASP.NET MVC to combine and compact CSS files and JavaScript files for pages on a website. For the most part this works as expected, however there are times (couple of times per week) when the HTTP handler responsible for returning the content returns an empty response and so pages load without any CSS - the HTML returns and the images load as well. When this happens, refreshing the page does not resolve the problem, while resetting IIS always resolves the problem. Also, without resetting IIS, after some time the problem stops.
Normally the script handler logs errors, however there are no errors logged during the issue. It seems as if the handler is never invoked. There are no failed request logs generated by IIS.
I monitored resource usage when this was happening and did not notice anything out of the ordinary. The web server is running IIS 7 and has low CPU usage. I increased some parameters in IIS settings regarding the number of allowable requests to process, the problem still exists though perhaps less frequent. The website receives about 1.5 million pageviews monthly.
I have a 'classic' ASP.NET app (.NET 3.5) with a pretty standard runat="server" style form with server-side controls and an 'Execute' asp:button. In the code-behind, the executeButton_click handler processes some of the other controls, runs a report, and drops the result into an asp:label. So the effect of pressing the Execute button is that the entire page reloads with the report inserted into the label.
I need to change this so that when the Execute button is pressed, the report pops up in a new window with a different layout (ie without the controls and form). If I was doing this in an MVC framework I would just change the view template in the 'execute' action, so the analogue for ASP.NET would be change the code in front, ie the .aspx file that gets used, from the code-behind class.
Is this possible? I know the link between the .aspx and the .aspx.cs isn't extremely tight as it is possible to reuse a code-behind class in multiple .aspx files. So can I set the .aspx file to render from the code-behind?
I'm moving applications from IIS6 to IIS7.5 (win 7 an win server 2008 r2), when 2 applications (with identity impersonate) try to get a file with response.writefile only from a UNC path i'll get "access denied". In IIS6 and Visual Studio Developer Web Server, same code works. I can save file with FilePath.SaveAs and get name and length with FileInfo, but not download. After 2 days of nightmares I have tried to change
Response.WriteFile(filePath)
to
Response.BinaryWrite(File.ReadAllBytes(filePath))
and now work. My question is: can I have a microsoft developer to sacrificate for my avenge?)
I'm getting this message when going to a web app that accesses my service.
"The content type text/html of the response message does not match the content type of the binding (text/xml; charset=utf-8)..."
The thing is, it happens once in a while even when no changes have been made to the service or the web app. And I can make it go away most of the time by going directly to the .svc?wsdl page in my browser and then coming back to the web app.
As I understand it, in IIS7 if I can get to it I should see both custom additions in my web.config as well as the mime types defined in the IIS manager at the machine level.
I don't understand how to get to this data. I have messed with the configurationmanager but I am not getting anywhere. I can get a section names system.webServer but I don't see any of the actual data as colleciton of properties or as xml.
I have a simple web site with two pages. One displays a list of files, and the other streams a file when it's clicked in the list. All was fine in production for 6 months, but now I have to move the site to Windows 2008/IIS7. I have it mostly working, but the files don't open properly (in Firefox) because my content-type header is being ignored. On the production site (IIS6) the headers are (using Fiddler):
HTTP/1.1 200 OK Date: Tue, 09 Feb 2010 16:00:51 GMT Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET X-AspNet-Version: 2.0.50727 Content-Disposition: attachment; filename="myfile__foo.pdf" Content-Length: 236841 Cache-Control: no-cache, no-store Pragma: no-cache Expires: -1 Content-Type: application/octet-stream
I've been having some production runtime errors that I don't fully understand. This has happened to us on a couple different ASP.NET 4.0 Web Sites (shudders - yes, I know - we're porting it to MVC but that's taking some time).
First of all, we have never been able to reproduce this issue in development/QA environments. Secondly, upon deployment, the issue seems to be non-existent. Sometimes the issue manifests within a day or two of deployment and other times the deployment will be live for a month without it manifesting at all. However, once it manifests, then ANY page viewed under the web site causes the error. Lastly, this problem seemed to only come up once we migrated to .NET 4.0. We started at 2.0, a year ago upped to 3.5, and recently upped to 4.0 with this solution and most child projects.
The error:
Could not find the sitemap node with URL '~/Default.aspx'.
A simplified version of our sitemap (with some names changed and uninteresting nodes removed) is as follows:
I have confirmed in all of the SiteMaps that there is a node with url="~/Default.aspx" with roles="*" (which includes public/anonymous access), so I am very confused as to why this problem occurs.
SiteMap does not have a node for Default.aspx. All of them do. SiteMap's Default.aspx node is not accessible for security reasons to the current user/role. They're all accessible to anonymous users and this problem even exists for super admin users. Passed-in URL contains querystrings (Default.aspx?abcd). I don't know if this is a problem (I sure would hope not) but once the problem manifests itself, I can handwrite the URL with no querystrings and the problem still exists.
SiteMap changes. It doesn't Service's permissions to the sitemap file. The sitemap works perfectly fine after a deployment, so unless permissions are changed in a way that IISRESET fixes, then this is not an issue. The worker process becomes globally corrupt. I don't think so. We have ~12 web sites all in the same app pool and the problem always stays confined within a single web site. Also, we have yet to have this happen to more than a single web site at a time although it has manifested itself in 4 different ones so far.
I have a working web app that uses a web service which is compiled into its separate assembly. I have another class library project compiled as a separate assembly that serves as a proxy to this web service. This all seems to work at runtime but I am getting this warning at compile time which I don't understand and would like to fix:
I have dozens of webforms in the main project that reference the proxy class with no compile time complaints as this snippet shows:
[Code]....
And yet I have one webform (also in the root of the main project) which gives me the "not CLS-compliant" message but yet attempts to reference the proxy class just like the other ASPX files. I get the compile time warning on the line annoted by me with 'ERROR here..
[Code]....
This makes no sense to me. The file with the warning is called frmHome.aspx.vb; all others in the project declare things the same way and have no warning. BTW, the webservice itself returns standard datatypes: integer, string, and dataset.
How can I change the chart type of the chart control in ASP.NET 4. I have a drop down list that contains name of all the chart types. This is the code I came up with :
[URL]I know how to remove the Server response header with an HTTP Module based on the link above. I just want to know why it is necessary to remove it this way.
I am using IIS7's URLRewrite feature to hide the .aspx extension in my ASP.NET WebForms application's URLs.
I'm using the following configuration:
[code]....
I can now browse to:
[URL]
and this is rewritten to:
[URL]
This preserves the "pretty" url in the browser address bar. I have also updated all my links on the site to use the extensionless URLs.
The problem is that the underlying .aspx pages can still be accessed directly and I'd like to prevent this.
If a user browses to [URL] I'd like it to either redirect/rewrite to [URL], or at the very least just return a "Page not found".
Update:
I managed to get this working by redirecting all .aspx pages to the home directory. This isn't ideal as I'd prefer to send them to the non-.aspx version, but it will do for now.
