Its simple: Browsers (Firefox works the same) query `GET http://wpad/wpad.dat`.

If a web server named wpad is resolveable, it should serve wpad.dat, a script file analog to netscape PAC files. MIME type must also be &quot;application/x-ns-proxy-autoconfig&quot;.

This [info][1] about WPAD (Web Proxy Auto Discovery) seems to describe the process in detail, though I have confirmed that what Tomalak says is also actually occurring.

The IE configuration described enables a WPAD implementation. Here&#39;s the [Microsoft explanation of the entire mechanism][1] (probably too much detail for a single post).

When Windows Internet Properties -&gt; Connections -&gt; LAN Settings -&gt; Automatic Configuration is set to &quot;Automatically detect settings&quot; how does Windows actually determine/discover what the settings are? Is it a network broadcast or some kind of targeted query to a server configured somewhere in the registry, or something else?

Often WinDbg will enter a state where it is  **\*Busy\*** performing an operation. 

Often this is due to some mistake I made trying to *dt some_variable_itll_never_find* or setting a break point somewhere without symbols or the 1000&#39;s of other mistakes I make fumbling around this tool.

**Is there a way to cancel the current operation?**

Is there any way to set a system wide memory limit a process can use in Windows XP? I have a couple of unstable apps which do work ok for most of the time but can hit a bug which results in eating whole memory in a matter of seconds (or at least I suppose that&#39;s it). This results in a hard reset as Windows becomes totally unresponsive and I lose my work.

I would like to be able to do something like the /etc/limits on Linux - setting M90, for instance (to set 90% max memory for a single user to allocate). So the system gets the remaining 10% no matter what.

I&#39;m using:

    FileInfo(
        System.Environment.GetFolderPath(
            System.Environment.SpecialFolder.ProgramFiles) 
        + @&quot;\MyInstalledApp&quot;

In order to determine if a program is detected on a users machine (it&#39;s not ideal, but the program I&#39;m looking for is a right old kludge of a MS-DOS application, and I couldn&#39;t think of another method).

On Windows XP and 32-bit versions of Windows Vista this works fine. However, on x64 Windows Vista the code returns the x64 Program Files folder, whereas the application is installed in Program Files x86. Is there a way to programatically return the path to Program Files x86 without hard wiring &quot;C:\Program Files (x86)&quot;?

What is the difference between a proxy server and a reverse proxy server?



What&#39;s the difference between a proxy server and a reverse proxy server?

I have downloaded Privoxy few weeks ago and for the fun I was curious to know how a simple version of it can be done.

I understand that I need to configure the browser (client) to send request to the proxy. The proxy send the request to the web (let say it&#39;s a http proxy). The proxy will receive the answer... but how can the proxy send back the request to the browser (client)?

I have search on the web for C# and http proxy but haven&#39;t found something that let me understand how it works behind the scene correctly. (I believe I do not want a reverse proxy but I am not sure).

Does any of you have some explication or some information that will let me continue this small project?

## Update
This is what I understand (see graphic below). 

**Step 1** I configure the client (browser) for all request to be send to 127.0.0.1 at the port the Proxy listen. This way, request will be not sent to the Internet directly but will be processed by the proxy.

**Step2** The proxy see a new connection, read the HTTP header and see the request he must executes. He executes the request.

**Step3** The proxy receive an answer from the request. Now he must send the answer from the web to the client but how???

How to create a simple proxy in C#?

The following code works for me:

    var webProxy = WebProxy.GetDefaultProxy();
    webProxy.UseDefaultCredentials = true;
    WebRequest.DefaultWebProxy = webProxy;

Unfortunately, `WebProxy.GetDefaultProxy()` is deprecated.  What else should I be doing?

(using app.config to set the defaultProxy settings is not allowed in my deployment)

How should I set the default proxy to use default credentials?

I&#39;m trying to trouble shoot a web service client in my current project.  I&#39;m not sure of the platform of the Service Server (Most likely LAMP).  I believe there is a fault on their side of the fence as i have eliminated the potential issues with my client.  The client is a standard ASMX type web reference proxy auto generated from the service WSDL.

How do I allow any device, e.g., iPhone, to connect over a WLAN to my Mac&#39;s localhost server?

On my Mac, I&#39;m running a &quot;Hello World&quot; HTTP [Node.js][1] server that serves a page, which Safari opens successfully, at `http://localhost:1337`. And, running `ipconfig getifaddr en1` in Terminal outputs `192.168.1.9`.

But, Safari, on both iPhone &amp; Mac, displays &quot;Safari can&#39;t connect to the server&quot; when it tries to open `http://192.168.1.9:1337`.

I don&#39;t think this should involve [port forwarding][2] because I only want the HTTP server to be available privately, not publicly.

How to get a list of all valid IP addresses in a local network?

First of all, I read at least 20 articles about this topic, and not one of them can match up the scenario and I screwed up the process numerous times. So I turn help by offering my specific scenario if any help will be appreciated.

Laptops or other devices are connected through a wireless router.

I&#39;ve tried:

- Enable Port 80 on firewall. nothing happened.
- Run `ping`, `ipconfig` and tried IPv4 address there, denied access or bring me to verizon (my ISP), router config page.
- Tried config Apache, was a mess, never get all the authorization setup in numerous posts and tried one of promising one, which crashed my WAMP, have to went through all the trouble and reinstall.

What I really tried to accomplish is really simply allow all users connect to that wireless router be able to acces my Win8 hosted WAMP sites.

I wonder if there is any specific steps that I can walk through to make it really work?

WAMP 2.4 on Win8.1.
