I'm writing a multi-tenant app that will receive requests like http://www.tenant1.com/content/images/logo.gif and http://www.anothertenant.com/content/images/logo.gif. I want the requests to actually map to the folder location /content/tenant1/images/logo.gif and /content/anothertenant/images/logo.gif
I'm using asp.net Mvc 2 so I'm sure there's probably a way to setup a route to handle this or a custom route handler?
I have a httphandler that is fitred for all .png files. I would to be able to rewite the name of the file into the html. Is this possible? So if test.png comes into the handler I want to write test.png?V=1
So far I have found the following:
context.Response.AddHeader("content-disposition", "inline; filename=" + context.Request.FilePath + "?V=1");
I have implemented my own IRouteHandler for URL routing. For files without extension it will try to load the filename as a Page from the Pages directory with:
return (IHttpHandler) BuildManager.CreateInstanceFromVirtualPath(path, typeof(Page));
However there are also images and css files (with relative paths) that need to be translated to the correct url. I try to service those files with:
try {
HttpContext.Current.Server.Transfer(fileName);
} catch (HttpException) {
throw new HttpException(404, "file not found");
}
This works fine (in Internet Explorer), however Firefox is giving me an error:
Styles.css was not loaded because its MIME type, "text/html", is not "text/css".
Is this caused by the Server.Transfer? What should I use to redirect the file? Response.Redirect is visible to the client.
Is it possible to register a custom httphandler in a stand alone assembly? I'm writing a control toolkit that uses httphandlers to perform AJAX and I would like to make the use of the toolkit as low friction for the web developers as possible. There will be quite a few handlers and I dont want the developer to have to register them all in the web.config.
View 2 RepliesI have an HttpModule and I'd like to choose the HttpHandler for the current request, is that possible? Also web.config is not an option because the condition is not based on path or extension. My googling skills have failed me, no matter what keywords I use all the results are "IHttpHandler vs IHttpModule".
View 3 RepliesI developed a .Net 3.5 x64 web application that includes a custom HttpHandler in the config:
<add path="*.class1" verb="GET" type="ClassLibrary1.Class1Handler"/>
This works when the platform target for ClassLibrary1 is set at x86.
However, when I set this to x64 I get the following error when I run web application starts (it compiles just fine): Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. Parser Error Message: Could not load file or assembly 'ClassLibrary1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format.
Does this mean that a HttpHandler can be compiled at x86 only?That doesn't make much sense to me.Does anyone have an idea of what could be going on?Edit 1:The ClassLibrary1 project is just an empty class library project with a single HttpHandler added (which is also empty).Edit 2:I am also getting these warning messages when compiling, I am pretty sure they have something to do with this problem: Assembly generation -- Referenced assembly 'mscorlib.dll' targets a different processor HttpTestEdit 3:I manually edited the project file to force references to the x64 assemblies, like this:
<Reference Include="$(Windir)Microsoft.NETFramework64v2.0.50727System.dll"/>
This does supress the above warning message, but the problem isn't resolved.
I'm trying to get custom HttpHandler working in my sample web application. I've been experiencing a lot of issues, but finally got stuck with error 500. Application pool is being run in Classic ASP.NET 2.0 mode. Server is IIS 7.5, OS is Win 7 Pro.
Here's a code of my handler:

I'm using a custom ashx HttpHandler to retrieve gif images from a database and show it on a website - when the image exists, it works great.
However, there are cases when the image will not exist, and I'd like to have the html table holding the image to become invisible so the "image not found" icon is not shown.

I create a custom http handler to block download of .wmv files e.g. www.pakdev.net/videos/file.wmv (blocked by httpHandler).
But the problem is that now silverlight cannot also stream these video files as they are blocked too.
On my website, www.pakdev.net, I create screencasts to which are streamed through silverlight.
I create a custom handler to block the download of .wmv files from the url like [URL]
But the problem is now the silverlight has also stopped streaming files.
I'm trying to secure my web application so XML files it contains can't be downloaded. I thought it would be as simple as adding these to the "httpHandlers" section of web.config:
<remove verb="*" path="*.xml"/>
<add verb="*" path="*.xml" type="System.Web.HttpForbiddenHandler"/>
This failed - the XML files could still be downloaded easily. I tried different browsers in case they were caching, but everything could download the XML files without any trouble. I thought this might be due to some special handling of XML, so I tried mocking up an alternative based on ".txt123" files. I added this file with some dummy content:

We have a handler to deal with .dat files.. everything is already setup and server is acknowledging the file type and doing its thing to handle it..
But the handler requires 1 bit of information along with the HTTP request which is a physical file path.. the file name it knows based on the file we call , but how can i pass a custom header along with the request so that the handler will use that when the request is made?
Basically when on our player.aspx page, i will have a button, when you click that button a request is made to the .dat file, but along with that request i need to send the physical file path.. how can i do that?
Considering the recent ASP.NET vulnerability, what should I look for in my httphandlers that would cause such a Padding Oracle vulnerability?
Asked in another way... what did MSFT do wrong and what did they fix in their handlers?
I'm creating a custom server control which needs to take in a root-relative path for one of it's properties. I use the UrlProperty, but when I select a file in the markup, the selected path doesn't inlcude the the "~/". I'd like to mimic the behavior of a hyperlink. So let's say I have this:
<asp:HyperLink ID="HyperLink1" NavigateUrl
When I type in an equals sign after the NavigateUrl property, intellisense pops open a URL picker and I can pick from any page to produce this code:
<asp:HyperLink ID="HyperLink1" NavigateUrl="~/default.aspx"
this code has the "~/" in front. When I use my control, I have this:
<cc1:TestControl ID="TestControl1" Url="default.aspx"
the C# code has this property:
[UrlProperty]
public string Url { get; set; }
Does anyone know how I can make the "~/" be placed in front to make a root-relative path?
I have an user control that reads the data from app_data folder and does some processing.In design time I'd like to show the row data in control placeholder (using GetDesignTimeHtml).To do that I need to figure out the absolute path to app_data folder on my project.The HttpContext is not available and HostingEnvironment.MapPath returns null.

I need to give reference to our header and footer for the outside vendor to reference. I am getting the following error.Parser Error Description: An error occurred during the parsing of a resource required to service this request.

The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.The file does exist. I am assuming the 404 error has to do with the ascx page not having opening and closing html tags. The page is referenced in our locally hosted pages as follows and works fine.
<%@ Register Src="~/CorporateHeadLinks.ascx" TagName="HLinks" TagPrefix="HeadLinks" %>
Is there an IIS setting I am missing or does the reference need to be done differently? My webserver is Windows Server 2008.
I have some user controls registered in the web.config.
Now I need to load some of them dynamiclly with the page.loadcontrol() function. This function needs a virtual path to the .ascx file. Is it possible to get this virtual path (that is the same as the source path in the config) by the tagname?
Exsits any way to modify the temporary folder path returned by System.IO.Path.GetTempPath() method?

I have a custom ASP.NET application that I utilize for several clients that I host. Each client has a separate domain and the application is normally a child application under the root domain [URL]. The application files are the same (aspx, ascx, style sheets, images, etc.). The only thing different is the web.config file for each client. As development of the application continues to evolve, I have to update the application for each directory and this obviously becoming tedious. I am trying to come up with a method keep the application up to date. My first though is placing the application into a single physical path and creating multiple applications pointing to that path (the problem with this method is I can't have different web.config files). I am curious as to what solution others are using in this scenario...

View 2 RepliesWhen I press start on my VS2010/Silverlight/C# project, it opens a new instance of the included webserver and opens my browser window so I can test the application. Unfortunately something has happened and I am not sure what it was.. The browser window now opens the starting page with a local machine path (C:...page.aspx) rather than the normal webserver path through http (http://localhost:33592/page.aspx). It is a Silverlight Navigation project using c#/asp.net code behind.
View 2 RepliesI am trying to convert the virtual path to a physical path but don't seem to have Server.MapPath or HttpServerUtility.MapPath available in my handler. I add the System.Web namespace with no luck.
string virtualTargetFolder = String.Format("~/UserImages/{0}/Images/", user.ProviderUserKey.ToString());
string physicalTargetFolder = System.Web.HttpServerUtility.MapPath (virtualTargetFolder);
I had applied the following code as said by you :
byte[] b = YourByteArrayFromDb;
File.WriteAllBytes(MyFilePath, b);
But I am receiving an exception "Access to the path is denied". How do I solve this using ASP.Net with C#? And is there any format to set the path as string?
