Changing the Application Behavior
The Behavior area modifies how the application interacts with the user. Changing a property here will modify the way the application performs its task. The following list describes each of the properties in this area and describes how you can work with them (the configuration name appears in parentheses behind the friendly name).
Code Page (codePage) A code page is the set of characters that IIS uses to represent different languages and identities. English uses one code page, Greek another. Setting the code page to a specific value helps your application support the language of the caller. You can find a wealth of information, along with all of the standard code page numbers, at http://www.tipsandtutorials.net/unicode/codepages.html . IIS only understands the Windows code pages defined at http://www.tipsandtutorials.net/unicode/codepages.html#msftwindows . The default setting of 0 requests the code page from the client, which may or may not be a good idea depending on the structure of your application. If you plan to support specific languages using different parts of your Web site, always set the code page to obtain better results.
Enable Buffering (bufferingOn)
Buffering is the process of using a little memory to smooth the transfer of data from the ASP application to the caller. Using this technique makes the application run more efficiently, but does cost some additional memory to gain the benefit. Generally, you’ll find that buffering is a good investment on any machine that can support it and should keep this setting set to True (the default state).
Enable Chunked Encoding (enableChunkedEncoding)
Chunked transfers convert the body of a Web page into small pieces that the server can send to the caller more efficiently than sending the entire Web page. In addition, the caller receives a little of the Web page at a time so it’s easier to see progress as the Web page loads. You can learn more about this HTTP 1.1 technology at http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html. This value defaults to True.
Enable HTML Fallback (enableAspHtmlFallback)
Sometimes your server will get busy. If the server gets too busy to serve your ASP application, you can create an alternative HTML file that contains a static version of the ASP application. The name of the HTML file must contain _asp in it. For example, if you create an ASP application named Hello.ASP, then the HTML equivalent is Hello_asp.HTML. This value defaults to True.
Enable Parent Paths (enableParentPaths)
Depending on the setup of your Web server, you might want an ASP application to reference a parent directory instead of the current directory using the relative path nomenclature of ..\MyResource, where MyResource is a resource you want to access. For example, the ASP application may reside as a subfolder of a main Web site folder. You may want to access resources in that main folder. Keeping the ASP application in a subfolder has security advantages because you can secure the ASP application folder at a stricter level than the main folder. In most cases, however, the resources for the ASP application reside at lower levels in the directory hierarchy. Consequently, this value defaults to False.
