Ensure Correct URL Redirection in ASP.NET on IIS with R

To fix issues with Response.Redirect not including the application root folder in IIS, use ResolveUrl to ensure correct path resolution relative to the app root, or manually construct the URL with Request.ApplicationPath. For absolute paths, ensure they include the full application path.

Here is the issue you're encountering with Response.Redirect not correctly including the myApp root folder in the URL is likely due to how the path is being resolved in the IIS environment. Here's how you can fix it:

1. Use ResolveUrl in Response.Redirect

ResolveUrl helps in resolving the correct path based on the application root, ensuring that the myApp folder is included in the URL.

protected void Test_RedirectSSM(object sender, EventArgs e)
{
    string url = ResolveUrl("~/UserPages/TestareSSM.aspx");
    Response.Redirect(url);
}

2. Use Request.ApplicationPath

Another approach is to manually build the URL using Request.ApplicationPath, which will ensure that the application’s root folder (myApp) is correctly prefixed in the URL.

protected void Test_RedirectSSM(object sender, EventArgs e)
{
    string url = $"{Request.ApplicationPath}/UserPages/TestareSSM.aspx";
    Response.Redirect(url);
}

3. Absolute Path

If you are dealing with a situation where you must use an absolute path, ensure you correctly structure it, including the full application path:

protected void Test_RedirectSSM(object sender, EventArgs e)
{
    Response.Redirect("https://iis/myApp/UserPages/TestareSSM.aspx");
}

Summary

• ResolveUrl("~/...") is often the most reliable and easiest way to ensure URLs are correctly resolved relative to the application root.
• Request.ApplicationPath can be used to dynamically construct paths based on where your application is deployed.
• Ensure that any absolute URLs used include the entire path, including the myApp portion.

These approaches should help ensure that the redirect URL correctly includes your application's root folder (myApp) when deploying on IIS.
