How to print similar information as phpinfo() but for ASP.NET?

StackOverflow https://stackoverflow.com/questions/544209

Question

I've looped over the Request.ServerVariables collection in ASP.NET, but it's not as comprehensive as phpinfo().

How can I print all that information, including server software, drivers, etc, for ASP.NET?

Was it helpful?

Solution

An empty page with this header should do the trick:

<%@ Page Trace="true"  Language="C#" 
    ContentType="text/html" ResponseEncoding="utf-8" %>

The project is a ASP.Net System Information Prober. It's a single page which trying to get as much as possible of useful hosting information. The concept is similar to PHP page which contains phpinfo()...

ServerInfo.GetHtml() is basically the same as phpinfo(). Not only is the actual returned information extremely similar but also the html presentation. Here is a live demo!

You can also use it even if you're only making a pure Web API app, but letting a controller return a HttpResponseMessage like so:

    public System.Net.Http.HttpResponseMessage Get()
    {
        var serverinfo = System.Web.Helpers.ServerInfo.GetHtml().ToHtmlString();
        var response = new System.Net.Http.HttpResponseMessage();
        response.Content = new System.Net.Http.StringContent("<html><body>" + serverinfo + "</body></html>");
        response.Content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("text/html");
        return response;
    }

How about using the ASP.Net tracing subsystem? It allows you to get:

Control Tree: Control tree presents an HTML representation of the ASP.NET Control Tree. Shows each control's ID, run time type, the number of bytes it took to be rendered, and the bytes it requires in View State and Control State.

Session State: Lists all the keys for a particular user's session, their types and their values.

Application State: Lists all the keys in the current application's Application object and their type and values.

Request Cookies: Lists all the cookies passed in during the page is requested.

Response Cookies: Lists all the cookies that were passed back during the page's response.

Headers Collection: Shows all the headers that might be passed in during the request from the browser, including Accept-Encoding, indicating whether the browser supports the compressed HTTP responses and Accept languages.

Form Collection: Displays a complete dump of the Form Collection and all its keys and values.

QueryString Collection: Displays a dump of the Querystring collection and all its contained keys and values.

Server Variables: A complete dump of name-value pairs of everything that the web server knows about the application.

Have a look at glimpse.

glimpse: A client side Glimpse to your server

What Firebug is for the client, Glimpse does for the server... in other words, a client side Glimpse into whats going on in your server.

Here's the request tab as shown in the browser.
(source: getglimpse.com)

There are other tabs with information, and it's possible to write plugins.

The following might work?

foreach (string Key in Request.ServerVariables.AllKeys) 
   Response.Write(Key + ": " + Request.ServerVariables[Key] + "<br>");

I'm not sure what info phpinfo() spits out.

here is an answer i found, that looks like it covers it covers it, at first sight: http://www.actionscript.org/forums/showthread.php3?p=133347 someone scripted it out

According to them, the answer is no.

For ASP classic with VBScript (not ASP.net - see disclaimer below) there is a Sub aspinfo() on Planet Source Code, to which I've made very minor changes (moving the call to aspinfo() and moving the top authorship/comment block).

Here is the source of my modified version of Dennis Pallett's aspinfo(), which can be saved as aspinfo.asp on the webserver in question.

<%@ Language="VBSCRIPT" %>

Disclaimer: Note that this was initially submitted as an edit to Rob's answer, but it was suggested that it be made as an entirely new answer response instead. Note also that, as frankadelic points out in a comment to Rob's answer, this response doesn't address the OP's question, as that question was for ASP.net, not ASP classic.

I realized a simple library to inlude in projects called InfoPage. This library show you system info, assembly included in application, build number,and changelogs.

You can simply include it in your project by nuget, it is quick to integrate and customizable.
