By default, HttpWebRequest will not attempt to authenticate the client to the server, even in integrated authentication scenarios. (So it has a different default policy than Internet Explorer IE will automatically authenticate you to servers on your local network with integrated authentication, but HttpWebRequest will not.) If you re writing client code and you want it to identify the user to the server, you must set the request s Credentials property. For integrated authentication, there s a special credentials object to represent the user s identity, provided by the CredentialCache class. Example 13-16 shows how to use this to enable integrated authentication. (Obviously, this will only do anything if the server is prepared to use it so this code merely tells HttpWebRequest that we re happy to use integrated authentication if the server asks for it. If the server turns out not to require authentication at all, you won t see an error.)

update itself by querying CPAN sites when run for the first time and while downloading the Perl modules. Also, if you need to reconfigure your CPAN shell network settings, you can run the command o conf init while on it.

HttpWebRequest request = (HttpWebRequest) WebRequest.Create("http://intraweb/"); request.Credentials = CredentialCache.DefaultCredentials; ...

HTTP authentication isn t always integrated with Windows security. It also supports username- and password-based authentication. The HTTP specification supports two ways of using this. Basic authentication just sends your username and password as part of the request, so unless you re using HTTPS, that s not very secure. The alternative, digest authentication, is better, but seems to be rarely used. In practice, basic authentication over HTTPS seems to be the popular choice. For either kind of authentication, you specify the username and password in the way shown in Example 13-17.

HttpWebRequest request = (HttpWebRequest) WebRequest.Create("https://intraweb/"); request.Credentials = new NetworkCredential("user1", "p@ssw0rd"); ...

Install each required module using the CPAN shell prompt with the install command: install module_name where module_name is the name of the Perl module that you want to install in your system. For example, to install the Crypt::SmbHash module, you will use install Crypt::SmbHash at the CPAN prompt. You will see a lot of output, including the current progress of the module s download and compilation if necessary. There will be times where CPAN will ask you for additional information during installation, such as when you are running tests or installing additional modules. A sample question is shown in Figure 16-14.

This approach doesn t let you specify whether to use basic or digest authentication because the server gets to choose. Since you therefore don t know whether the password will be sent in the clear, you should normally provide credentials this way only when using HTTPS. You can force the use of digest authentication by wrapping the Network Credential in a CredentialCache object, which lets you specify the authentication schemes you want to support. Even so, you might want to be wary of using digest authentication without HTTPS although digest authentication can be secure, some servers implement it in an unsecure way.

By default, web requests will look at the Internet Explorer settings to determine whether a web proxy should be used. But you might not want this default behavior, so there are a couple of ways you can change it.

Figure 16-14. An additional module to be installed in your system It is safe to accept the defaults and press Enter each time you are asked. After the installation completes, you will be given back your CPAN prompt. Use the install command again for the Digest::SHA1, Net::LDAP, and Unicode::MapUTF8 modules.

Prior to .NET 2.0, IE proxy settings weren t honored, so you may occasionally come across code that goes to some lengths to work out whether it needs to use a proxy. Usually such code is either old or written by someone who didn t know that .NET 2.0 fixed this issue.

You can add entries to your App.config file to modify the default proxy behavior. Example 13-18 stops web requests using the configured default proxy by default.

The default behavior, in the absence of any configuration, specifies that the use of the default proxy is enabled, but the application will not use the user s credentials to identify the user to the proxy server. (Authenticating the user to a proxy happens independently of authenticating the user to the web server.) Some companies require users to authenticate with the proxy in order to access the Internet, in which case you would need to change the configuration, setting the <defaultProxy> element s useDefaultCre dentials attribute to true. You can also modify the behavior in code. The HttpWebRequest class has a Proxy property, and you can set this to null to disable the use of a proxy. Or you can set it to a WebProxy object specifying a specific proxy and settings, as Example 13-19 shows.
