ASP.NET-MVC – MVC lasts the opportunity to change the response to the user

public class CompressFilter: ActionFilterAttribute
{
 public override void OnActionExecuting(ActionExecutingContext filterContext)
 {
 HttpRequestBase request = filterContext.HttpContext.Request;

 string acceptEncoding = request.Headers["Accept-Encoding"];
< br /> if (string.IsNullOrEmpty(acceptEncoding)) return;

 acceptEncoding = acceptEncoding.ToUpperInvariant();

 HttpResponseBase response = filterContext.HttpContext.Response;

 if (acceptEncoding.Contains("GZIP"))
 {
 response.AppendHeader("Content-encoding", "gzip");
 response.Filter = new GZipStream (response.Filter, CompressionMode.Compress);
 }
 else if (acceptEncoding.Contains("DEFLATE"))
 {
 response.AppendHeader("Content-encoding", "deflate");
 response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress);
 }
} 
}

[CompressFilter]
 // Minifies, compresses JavaScript files and stores the response in client (browser) cache for a day
 public JavaScriptResult GetJavaScript(string jsPath)

I need Change the complete html response stream (using html parsing) before it is presented to the user.
Where/when is the last chance?

IMHO, a better way to change the HTML response in the ASP.NET MVC environment is to use an action filter.
This is an action filter for compressing the output Example of a filter:

public class CompressFilter: ActionFilterAttribute
{
 public override void OnActionExecuting(ActionExecutingContext filterContext)
 {
 HttpRequestBase request = filterContext.HttpContext.Request;

 string acceptEncoding = request.Headers["Accept-Encoding"];

 if (string.IsNullOrEmpty(acceptEncoding)) return;

 acceptEncoding = acceptEncoding.ToUpperInvariant();

 HttpResponseBase response = filterContext.HttpContext.Response;

 if (acceptEncoding.Contains(" GZIP"))
 {
 response.AppendHeader("Content-encoding", "gzip");
 response.Filter = new GZipStream(response.Filter, CompressionMode.Compress);
 }
 else if (acceptEncoding.Contains("DEFLATE"))
 {
 response.AppendHeader("Conte nt-encoding", "deflate");
 response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress);
 }
 }
}

< p>You can use it on your action method:

[CompressFilter]
 // Minifies, compresses JavaScript files and stores the response in client (browser) cache for a day
 public JavaScriptResult GetJavaScript(string jsPath)
