HTTP Headers Property Sheet

Use the HTTP Headers properties to set values returned to the browser in the header of the HTML page.

Enable Content Expiration

Select this check box to include expiration information. Include a date in time-sensitive material, such as special offers or event announcements. The browser compares the current date to the expiration date to determine whether to display a cached page, or request an updated page from the server.

Custom Headers

Use this property to send a custom HTTP header from the Web server to the client browser. For example, you could use a custom HTTP header to allow the client browser to cache the page but prevent proxy servers from caching the page. Custom headers are described in the metabase.

To have your Web server send a header, click Add, and then type the name and value of the header in the text box.

To stop sending a header, select it and click Remove.

Content Ratings

Use content ratings to embed descriptive labels in the HTTP headers of your Web pages. Browsers, such as Microsoft Internet Explorer, version 3.0 or later, can detect content ratings to help users identify potentially objectionable Web content.

To set Ratings Property Sheet for a Web site, directory, or file, click Edit.

MIME Map

Click the Edit button to configure Multipurpose Internet Mail Extensions (MIME) mappings. These mappings set the various file types that the Web service returns to browsers. For more information, see MIME Map.

If you set MIME mappings in the master property sheets for your computer, the Web sites and directories on your computer use the same mappings. You can modify the MIME mappings for a Web site or directory. However, if you then reapply the master properties, the master properties completely replace the modified properties for the Web site or directory. That is, the properties are not merged.
