NET step by step. I am assuming that you have knowledge on ASP. Having knowledge on response filter is nice to have but it is not mandatory. In ASP. NET, all requests related to dynamic resources are handled by corresponding http handlers, same way the trace viewer request Trace.
Web namespace. With this information, we can add a handler configuration to web. But the problem is not solved completely because the trace handler injects the Trace.
NET called Response Filter which can alter the response before sending to the browser. Response filter is a specialized version of stream and it has options to read and write the response content.
The following diagram explains about the smart trace viewer life cycle in the ASP. NET application. If you have enabled tracing for your application, when any page is requested, the page gathers trace information and executes any trace statements that it contains. You can view the trace output in the trace viewer.
The trace viewer enables you to choose a specific request from the pages that have been requested from your application. When you enable tracing for an application, you can display trace output in any page in the application by setting the pageOutput attribute of the trace element to true in the Web.
If multiple requests have arrived for an application that has tracing enabled, the trace viewer lists the requests in the order in which they were processed. The information on the opening page of the trace viewer includes the time of the request, the file requested, the status code of the request, the HTTP verb associated with the request, and a View Details link that enables you to see more information about the request.
You can configure individual pages to display trace information. Alternatively, you can configure the application's Web. Setting application-level tracing is useful because you do not have to change individual pages to enable and disable it.
Trace statements are processed and displayed only when tracing is enabled. You can control whether tracing is displayed to a page, to the trace viewer, or both. NET Page. NET Application. You enable application-level tracing by using the trace element in the Web.
When you enable application-level tracing, ASP. NET collects trace information for each request to the application, up to the maximum number of requests you specify. The default number of requests is By default, when the trace viewer reaches its request limit, the application stops storing trace requests.
You can configure tracing to store the oldest tracing data discarding newer items or the most recent trace information discarding older items. When you enable tracing for the whole application in the Web. To override the application-wide settings, set the Trace attribute in that page's Page directive to false.
Any Write or Warn statements that you include in a page's code are stored and returned to the trace viewer only. You can view trace information at the bottom of individual pages. Alternatively, you can use the trace viewer Trace. NET when tracing is enabled. For details about what the trace display includes, see Reading ASP.
NET Trace Information later in this topic. If you want trace information to appear at the end of the page that it is associated with, you can set the trace element's PageOutput attribute to true. If you enable application-level tracing, but you do not want trace information displayed for some pages, you can set the Trace attribute in those pages' Page directive to false.
For more information about how to configure an ASP. NET Configuration Overview. By default, application-level tracing can be viewed only on the local Web server computer. To make application-level trace information visible from remote computers, you can set the trace element's LocalOnly attribute to false. To help keep the Web application secure, use the remote tracing capability only when you are developing or deploying your application.
Make sure that you disable it before you transfer your application to production Web servers. To do this, set the LocalOnly attribute to true in the Web. The following example shows an application trace configuration that collects trace information for up to 40 requests. It also enables browsers on computers other than the server to display the trace viewer. Active 12 years ago. Viewed 1k times. Add a comment. Active Oldest Votes.
