Migrating a Web Server to IIS 5.0

Resource Configuration

Table 3.3 Apache srm.conf Directives and Corresponding IIS 5.0 Properties

Apache Directive	Wizard Migrates (Y/N)	IIS Metabase Property	IIS Snap-in Configuration
AccessFileName	Yes	Not applicable	The wizard uses these parameters for mapping access configuration information. However, in IIS 5.0 there is no separate access configuration file. IIS 5.0 security is integrated with Windows 2000 security. To limit access to a site or directory by user, you must configure a new user account in the Windows 2000 Server User Manager. You can also classify individuals or groups as “Web site Operators” with limited authority to administer a Web site. They do not have to be Windows 2000 Administrators. To define Web site Operators, in the IIS snap-in right-click a Web site, click Properties, and then click the Operators tab.
AddDescription	No	Not applicable	There is no corresponding property in IIS 5.0.
AddEncoding	Yes	MimeMap	To map a file extension to a MIME type, right-click a Web site, choose Properties, and then select the HTTP Headers tab. In the Mime Map box, click File Types, and then click New Type. Or, to edit an existing MIME type, select a file type in the list, and then click Edit. Type the file extension and associated MIME type in the appropriate boxes.
AddIcon	No	Not applicable	IIS 5.0 uses the standard Windows 2000 icons when displaying a directory. You cannot specify a substitute icon.
AddLanguage	No	Not applicable	There is no corresponding property in IIS 5.0.
AddType	Yes	MimeMap	To add MIME types, right-click a Web site, choose Properties, and then select the HTTP Headers tab. In the Mime Map box, click File Types, and then click New Type. Type the file extension and the associated MIME type in the appropriate boxes.
Alias	Yes	Not applicable	The wizard creates a Virtual Directory object for each Apache alias and applies the appropriate parameters by configuring corresponding metabase properties. To create a virtual directory, right-click the FTP or Web site, click New, and select Virtual Directory. Use the New Virtual Directory Wizard to complete this task.
AliasMatch	Yes	Not applicable	There is no direct equivalent in IIS 5.0 because there is no concept of regular expressions. The wizard creates a corresponding Virtual Directory object. See the previous note for Alias.
DefaultIcon	No	Not applicable	Windows 2000 Server offers a standard default icon for file types that do not have a preset icon in the file system.
DefaultType	Yes	MimeMap	IIS 5.0 contains a comprehensive list of MIME types. You can add new MIME types to the list should you need to serve a new MIME type. To view default MIME types, right-click a Web site, choose Properties, and then select the HTTP Headers tab. Click the File Types button in the MIME Map section of the tab.
DirectoryIndex	Yes	EnableDirBrowsing	You can configure IIS 5.0 to allow directory browsing. To configure this setting, right-click a Web site, choose Properties, select the Home Directory tab, and then select the Directory Browsing check box. IIS 5.0 does not allow you to specify a prewritten HTML document as a directory index.
DocumentRoot	Yes	Path	The wizard migrates this directive to the Path property of the IIS Root object. This property defines the path from a Web site home directory to its corresponding physical directory. To configure this property, right-click a Web site, choose Properties, and select the Home Directory tab. Then specify the location of the home directory (document root).
ErrorDocument	Yes	HttpErrors	To enable custom error messages, right-click a Web site, choose Properties, and then select the Custom Errors tab. In cases where the custom error page is a standard HTML page, you need only copy the file to the IIS 5.0 system in order to complete the migration. In the case of CGI custom errors, you need to test the CGI scripts after moving them to IIS 5.0.
FancyIndexing	No	Not applicable	IIS 5.0 offers default indexing only.
HeaderName	No	Not applicable	There is no corresponding property in IIS 5.0.
IndexIgnore	No	Not applicable	There is no corresponding property in IIS 5.0.
LanguagePriority	No	Not applicable	There is no corresponding property in IIS 5.0.
MetaDir	No	Not applicable	You do not need to specify a Meta Directory to serve HTTP header information. To specify custom HTTP headers, right-click a Web site, choose Properties, select the HTTP Headers tab, and then click Add. Specify a header name and value in the appropriate boxes.
MetaSuffux	No	Not applicable	See the previous note for MetaDir.
ReadmeName	No	Not applicable	IIS 5.0 does not specify a default name for ReadMe files.
Redirect	Yes	HttpRedirect	To redirect a request to another resource, right-click a Web site, choose Properties, select the Home Directory tab, and then select A redirection to a URL. Type the URL in the Redirect to box.
RedirectTemp	Yes	HttpRedirect	In IIS 5.0, redirections are temporary by default.
RedirectPermanent	Yes	HttpRedirect	To make a redirection permanent, follow the steps previously given for Redirect. In addition, select the A permanent redirection for this resource check box after typing the URL.
ResourceConfig	Yes	Not applicable	The wizard uses this information, but it does not directly translate to an IIS 5.0 property.
ScriptAlias	Yes	Not applicable	The wizard creates a Virtual Directory object using the Apache path information and sets the IIS AccessExecute property to TRUE. Any virtual directory can execute scripts when the “Allow Scripts” permission is enabled in the IIS snap-in. To configure this property, right-click a Web site, choose Properties, select the Home Directory tab, and then select the Scripts only or the Scripts and Executables option in the Execute Permissions box.
TypesConfig	Yes	MimeMap	The wizard adds specified MIME types to the IIS 5.0 MIME map. To view or configure MIME types, right-click a Web site, choose Properties, and then select the HTTP Headers tab. Click the File Types button in the MIME Map section of the tab.
UserDir	No	Not applicable	IIS 5.0 does not offer a default directory for ISP user httpd directories. You must create a virtual directory for each user in the IIS snap-in, and then point it to the user directory in Windows Explorer.
