My default document is in subfolder not in root how can i make it default in asp.net 2.0 website.
Tried iis7 default document setting to '/pages/default.aspx'
'~/pages/default.aspx' but it didn't work.
Default document is not the same as start page. Default document means if I requested mysite.com/somefolder and didn't specify a file, which file should IIS display.
If you want to use a specific page as your home page, create a Default.aspx file and write this in it's codebehind class:
public override void ProcessRequest(HttpContext context) {
context.Response.Redirect("pages/default.aspx", true);
}
As the client might have disabled Javascript, a server side approach would be more reliable. However it's best to issue a permanent redirect instead of a simple Response.Redirect. Also doing it using JS will be bad from a SEO point of view.
You don't need to create a dummy Default.aspx page.
In your Global.asax.cs file, write the following:
public void Application_Start(object sender, EventArgs e)
{
var routeCollection = RouteTable.Routes;
routeCollection.MapPageRoute("DefaultRoute", string.Empty, "~/YourDesiredSubFolder/YourDesiredDocument.aspx");
}
Explanation:
Application_Start code is guaranteed to run once and only once on the application start.
The first line of code, gets a collection of the URL routes for your application.
The second line of code, defines a new route pointing to your inner page in the subfolder that you wish.
The second argument is empty to indicate that this route is used when there's no specific page is requested and there's no Default document existing.
Default documents are a subfolder-specific thing - what you're trying to do won't (directly) work. Set up a default.htm file in the root, and have it refresh to your real "home page".
The better question you should be asking is how on Earth your homepage got out of the root directory.
In theory you could have a Web.config file inside the directory and use the defaultDocument element to set the default document. See here: https://stackoverflow.com/a/2012079/125938.
Unfortunately I haven't been able to get it to work myself locally, but that might be because it isn't supported in the Visual Studio development server.
Say "index.html" is the default page you want and it is present in "Public" subfolder.
Instead of specifying "/Public/index.html" as the default site, try "Public/index.html"

My asp.net project, currently runs from http://localhost:51143/default.aspx
Is there anyway, I could include the root to this like http://localhost:51143/TOrders/default.aspx The reason I want to do this is because the URls that get called on the menu click events refer to "TOrders/Reports/aaa.aspx and so on and in production it would refer to intranet/TOrders/Reports/aaa.aspx and so on.
One solution could be to intercept every request in Application_BeginRequest method in Global.asax.
There you can create a rule to remove TOrders/ from the beginning. Try something like this:
void Application_BeginRequest(object sender, EventArgs e)
{
if (Request.RawUrl.StartsWith("TOrders/"))
Server.Transfer(Request.RawUrl.Substring(8));
}
This may not the nicest solution, but it should be enough to give you idea what to do.
Edit:
Since you have web project (not a web site), you can set virtual path of your project. I think this is what you are looking for.
If you are using VS2010, in Solution explorer right click on your project and chose Properties, then on Web tab, in Servers section, change virtual path of your project to /TOrders/ instead of / which is default value. Now you should get http://localhost:51143/TOrders/default.aspx
You need HttpRequest.ApplicationPath property
or HostingEnvironment.ApplicationVirtualPath property.
Also useful for building virtual paths is VirtualPathUtility class.
EDIT:
Try to copy your project into a subfolder of you web root, for eg. in IIS:
C:\inetpub\wwwroot\ (or what you set)
C:\inetpub\wwwroot\MyProject\
Now in IIS Managment Console, in your Default Web, you create a new 'Application'. Either you upgrade the existing folder or you create a virtual new one to your folder.
Then select a virtual path (TOrders) and set the physical path. There you will also set the AppPool if you have .NET 4, or select the runtime if you have 2.0/3.5 on IIS6.x. Try the highest version first...
Go to localhost/TOrders/
We have an application that has been developed by the third party, and I don't want to go back to them to get them to add in cache control for specific pages.
All the pages that need caching disabled are in a single directory.
The issue is that IE seems to not follow Cache-control:nocache properly, so we need to add in Pragma:nocache and cache age as well.
Is there a way to do this using configs in the directory? will it cascade through all child directories? Can it be done via the main web.config?
To be clear, I'm not looking for a way to do this via code, it needs to be via configuration of either IIS or the web.config files.
We're using ASP.NET 2.0 and 4.0, on IIS 6.0.
This can be done in IIS using the UI, it's actually quite easy, or atleast it was in my use case.
All you do is simply open up IIS manager, navigate to the site and then the directory you want to add the headers to Right Click -> properties.
Click the "Headers" tab, and add in the headers you require.
This goes recursively down the child directories, and adds the headers before any added by the code.
In IIS 7.0/7.5, you can use the StaticContent section of a web.config in each of the directories.
You can do that on global.asax
protected void Application_BeginRequest(Object sender, EventArgs e)
{
HttpApplication app = (HttpApplication)sender;
string cTheFile = HttpContext.Current.Request.Path;
if (cTheFile.Contains("/ExtraDir/"))
{
// add your header here
app.Response.AppendHeader("Pragma", "no-cache");
}
//... rest code of...
}
Application uses Forms authentication and has folders with excel files. Need to prevent
unauthorized, automated scripts or bots from accessing these folders. What would be best option to prevent this?
Have the authorization node of the lockElementsattribute value set in the
Web.config file.
Have a element added to the element in the Web.config
file.
3 Use (CAPTCHA) image control on each page of the application.
4 Use Robots.txt file implemented in the root directory of the application.
Have the Excel files mapped to the ASP.NET ISAPI filter.
Or are there better options? Httmodules?
You could protect the excel files by writing a custom httpmodule and validating that they are authed via the forms auth before giving them access to the file.
In addition I would use the robots.txt file as well to exclude them. Those that follow the rules will stop looking at that point. The rest will be taken care of with the custom httpmodule.
The most secure solution would be to store your files outside of the web-tree and then serve them up via a HttpHandler. The simplest handler to create in ASP.NET would be an .ashx Handler as outlined in this blog post.
Download File
Your handler would then check the user request to ensure the user is authenticated and then stream the file back. In simplified pseudo-C# code this would be something like:
public void ProcessRequest(HttpContext context)
{
string file = context.Request["file"];
if (user.IsAuthenticated())
{
OutputFile(file, context)
}
}
private void OutputFile(string file, HttpContext context)
{
string fileContent = LoadFileFromSecureDirectory(file);
Response.Output(fileContent);
}
Map the Excel files to the ASP.NET ISAPI filter and add a
<deny> element to the <authorization> element in web.config,
I have a asp page in which i have to display the image which is stored in my local disk C:
i.e..
C:\Program Files\Adrenalin\Adrenalin\UploadedFiles\TemplateFile\abc.jpg
how can i do that...i am not able to do so.
the image is not displayed instead it shows a empty image holder with the name of the image as specified and URL as not available.
Please help....
You will have problems with permissions if the image is outside of the web site folder. Traditionally, web sites run under the NETWORK SERVICE user account, which will limit access to files outside of the folder. You will need to extract the file from a folder with similar access and it is extremely unwise to do so, particularly from Program Files.
You should possibly proxy the file via a web page or web service, which doesn't expose the fact that the image is served external to the web site. You'll need to make sure the target folder C:\Program Files\Adrenalin\Adrenalin\UploadedFiles\TemplateFile has NETWORK SERVICE Read-access.
eg. create a blank ASP.NET page:
<%# Page Language="C#" AutoEventWireup="true" CodeFile="ImageServer.aspx.cs" Inherits="ImageServer" %>
with the code behind:
class ImageServer
{
void Page_Load(object sender, EVentArgs e)
{
Response.ContentType="image/jpeg"; // for JPEG file
string physicalFileName=#"C:\Program Files\Adrenalin\Adrenalin\UploadedFiles\TemplateFile\abc.jpg";
Response.WriteFile(physicalFileName);
}
}
And test in your browser by going to the URL
http://<localhost>/<website>/ImageServer.aspx
You should get the image.
Then, within the tag, use the URL of the page as your image placeholder:
<img src="ImageServer.aspx" alt="Image served" />
UPDATE:
Looking at your latest comments, I suggest you send a QueryString parameter with some sort of employee code and use that to query the database and get the appropriate filename within the Page_Load() method. Don't send the filename as part of the QueryString.
What you're trying to do can work, but it's highly discouraged in Web development. Putting the permissions problems aside (which are very serious), you can never assume that your images will be available in the absolute path you provided on drive C:.
What you should do, is create a folder inside your website directory and use it to store the images, and use relative links instead of absolute links.
Even if you manage to make absolute links work now, prepare yourself for sever headaches in the future when running your application in different configurations.
copy the image in your project root folder and provide the image source as only the name of the image instead of the complete path.
e.g., img src = "battlefield.jpg"
Where can I setup custom errors for directories in my application such as App_Code, App_Browsers, etc.? I already have customErrors configured in the web.config and that works as expected. For example,
http://www.mysite.com/bla.aspx > redirects to 404 page
but
http://www.mysite.com/App_Code/ > displays "The system cannot find the file specified."
There's no physical App_Code directory for my site. Is this something that I can change in IIS?
You are trying to server content from an Protected Folder... ??
I think you might need to allow access to these folders to get the nice errors you are looking for...
http://www.webdavsystem.com/server/documentation/hosting_iis_asp_net/protected_folders
That being said... there is a reason these folders are protected.
I would never put anything i needed IIS to serve in protected folders.
But there are always reasons to do do something? i have broke a few rules in my short lifespan :)
UPDATE:
Found this when i tried this locally: http://support.microsoft.com/kb/942047/
Looks like those reserved directories throw special 404's you might be able to get IIS to Target the 404.8 type... with out opening up serving to those directories
I believe you will need to set the error pages in IIS itself, as the requests you talk about never reach the ASP.NET application. The reason your first example works is because IIS recognises the .ASPX extension and forwards it to ASP.NET.
One way is to provide a redirect in the global.asax file:
void Application_Error(object sender, EventArgs e)
{
//uncomment this to narrow down 'helpful' microsoft messages
//HttpRequest request = ((HttpApplication)sender).Context.Request;
Exception ex = Server.GetLastError();
//ErrorManager is a custom error handling module
ErrorManager.ProcessError(ex);
Response.Redirect("~/error.aspx?error=" + HttpUtility.UrlEncode(ex.Message), true);
}
{ On a side note, I was getting an exception that I just couldn't track down - it just said 'file not found' but didn't say which file was missing. It turned out to be a broken image reference in a css file - breaking on line two of the code above helped identify the missing file }
Add a Wildcard Mapping to IIS to run ALL Requests through ASP.net, then you can use Global.asax to handle the error.
Taken from here:
Follow these steps to create a wildcard script map with IIS 6.0:
Right-click a website and select Properties
Select the Home Directory tab
Click the Configuration button
Select the Mappings tab
Click the Insert button (see Figure 4)
Paste the path to the aspnet_isapi.dll into the Executable field (you can copy this path from the script map for .aspx files)
Uncheck the checkbox labeled Verify that file exists
Click the OK button
