The wizard creates a solution, which contains two separate projects: a handler project and an ISAPI extension project.

This is a first for IIS and a fundamental improvement over the previously limited ISAPI extensibility model.

The project is created with a Web application DLL and an ISAPI extension DLL.

ATL Server does not provide direct support for ISAPI filters; it only provides support for ISAPI extensions.

The ISAPI extension forwards the request to an application domain within the ASP. NET worker process.

Prior to ASP. NET, URL rewriting on IIS Web servers needed to be implemented using an ISAPI filter.

Incidentally, specifically renaming all . asp scripts to . html works fine without modifying the ISAPI extension mapping.

Adds support for session-state services to the ISAPI extension, allowing the creation, storage and retrieval of data across requests.

However, we will discuss the tradeoffs between implementing URL rewriting as an ISAPI filter versus using techniques available in ASP. NET.

You can customize the code used to create the ISAPI extension DLL in the ISAPI extension project.

Allows an arbitrary number of HTTP modules handle the events that are raised, akin to IIS's ISAPI filters.

The ISAPI filters are quite common, inexpensive, and possess various features for selectively compressing content.

Gets or sets a value indicating the time interval at which the ISAPI extension pings the worker process to determine whether it is running.

When the ASP. NET ISAPI extension starts the worker process up, it passes a few command-line parameters.

Register Output is only valid for ISAPI extensions.

Choose the options to be supported by the ISAPI extension DLL.

Demonstrates how to retrieve the values of the server variables that IIS makes available to your ISAPI extension and request handlers.

As we discussed in the previous section, ISAPI filters can be created to respond to the events raised by IIS.

Adds performance counters for monitoring request statistics to the ISAPI extension.

The ISAPI extension transfers the request to an application domain inside the ASP. NET worker process.

IIS first checks which ISAPI extension can serve this request. Depending on file extension the request is processed.

Demonstrates the creation of an ISAPI filter using ATL Server's support classes.

When aspnet_isapi detects that the worker process is dead, it automatically aborts the request and frees any associated IIS resources.

The project is created without additional support options for the ISAPI extension DLL.

It allows the SOAP servers to share services exactly as those in an ISAPI DLL.

To guarantee optimal performance, aspnet_isapi uses asynchronous named pipes to forward requests to the worker process and to get responses.

If the default process model is enabled, aspnet_isapi queues the request and assigns it to the worker process.

TIP: ISAPI is a Microsoft technology, optimised for Microsoft websites (IIS).

This property should only be set to Yes when the primary project output is an ISAPI extension.

This wizard page describes the current project settings for the MFC ISAPI extension DLL you are creating.

The MFC ISAPI extension is an Internet Server API extension or filter.

This property should only be set when the primary project output is an ISAPI extension.

Provide the location of the generated ISAPI extension DLL project.

In the past, this has been one of the most error-prone and tedious areas for ISAPI development.

Since the ISAPI modules changed their names, from php4xxx to php5xxx, you need to make some changes in the configuration files.

When the request arrives, IIS examines the resource type and calls into the ASP. NET ISAPI extension.

An ISAPI extension is an unmanaged, compiled class that handles an incoming Web request.

For most scenarios, changing from using CGI to ISAPI will provide no noticeable benefit.

Generates code in the ISAPI extension DLL that supports additional services.

The ISAPI extension DLL does not return real stock data.

For instance, if the page is an '. ASPX page', then it will be passed to 'aspnet_isapi. dll' for processing.

The pool of threads and overlapped operations guarantee a good level of performance to the ASP. NET ISAPI.

You can further customize the ISAPI extension DLL project on the Server Options page.

Most Internet Server API (ISAPI) filters will also run without changes.

Existing content that uses IIS errors or a propriety ISAPI custom error mechanism would work unchanged.

They fall into two categories: ISAPI filters and external devices.

An error occurred registering the ISAPI extension .

The ISAPI-dll Module mapping should already exist but is disabled by default.

No action is necessary; Exchange Setup automatically configures the ISAPI extensions.

Delegates rendering the requested resource to an HTTP handler, which is akin to IIS's ISAPI extensions.

IIS is an unmanaged executable that provides an extensibility model based on ISAPI extension and filter modules.

ASP. NET HTTP modules are similar to ISAPI filters in that they run for all requests.

The ASP. NET ISAPI extension is a Win32 DLL and does not host managed code.

Like ISAPI extensions, ISAPI filters are blocks of unmanaged code installed on the Web server.

First, IIS receives the request and dispatches it to aspnet_isapi. dll.

At each state, IIS raises an event that can be programmatically handled using ISAPI filters.

When finished, the response is sent to aspnet_isapi opening an asynchronous pipe.

PipeBoost is an ISAPI filter and costs $1, 500 for an enterprise license.

Gateways are often CGI programs but may follow other standards such as ISAPI, Apache Module etc.

In no case, though, does the aspnet_isapi extension process the HTTP request.

ASP. NET is an ISAPI extension under the Web server.

All necessary HTTP application run-time services, such as ISAPI extension support, are equally available in any application pool.

This works flawlessly until you install ASP. NET 1. 1, which upgrades the extension mapping to the new version of aspnet_isapi. dll.

You can now easily do things in VB and C# that previously required writing a pretty gnarly C ISAPI.

With the ISAPI module, this is not a problem.

This system component is a Win32 DLL named aspnet_isapi. dll.

The Cognos 8 server engine can either use CGI or ISAPI (see section 7. 3 for more details).

In other web servers you need to change either the CGI or the ISAPI module filenames.

Refer back to section 3. 2 step 3 for instructions on how to make ISAPI work on a 64-bit IIS instance.

ISAPI filters, on the other hand, contain code to respond to events raised by IIS.
