The advice from UAError is only appropriate if the web site is on YOUR
computer. If you are trying to read the html contents of a page that is
running on someone else's computer, you will need to be able to log in to
that site. I assume you are talking about a situation where you can log in,
but you want to download the HTML to an application.
Most sites do what .Net does, and that is to make a login page available
that uses cookies. In this model, you log in to the server. The server
checks its database or directory for your credentials. If found, the server
issues a token. This is a string of characters to you, but means something
to the server. It provides that token to your site as a cookie.
All subsequent pages on the site require the cookie. Web browsers already
do this. If a cookie comes from a web site, with instructions for how long
the cookie should remain in the browser, the browser will automatically pass
the cookie back to every subsequent request from that web site.
So, your app has to pretend to be a browser. You have to use the GET and
POST methods of the HTTPWebRequest class to ask for the login page and to
provide the credentials. You will get back a collection of cookies. You
need to attach that cookie collection to all subsequent Web Requests against
that site.
So, look to the HTTPWebRequest HTTPWebResponse and CookieCollectio n classes
for further information on how to do what you want.
Note: you said you wanted to read the "source code" of the site. You will
be able to get the HTML, not the source code per se. If you want the C# or
ASP.NET code for a site, you will need direct access to the filesystem it is
on. That will normally require the cooperation of the system administrator.
In that case, my advice is meaningless. (I'm guessing here).
I hope this helps,

Hi All,
I use VC .Net 2003 and I want to create a small program which is able to
read the source code of a web site. I have a textbox with the URL, a
button and a multiline textbox for the source code. If the web page is secure,
how can I post my login details?
Any help appreciated.
Regards,
Nicolae
