Attributes

Attribute

Description

allowPathInfo

Optional Boolean attribute.

Specifies whether the handler processes full path information in a URI, such as contoso/marketing/imageGallery.aspx. If the value is true, the handler processes the full path, contoso/marketing/imageGallery. If the value is false, the handler processes only the last section of the path, /imageGallery.

The default value is false.

modules

Optional string attribute.

Specifies the name of the module or modules to which you want to map the file name or file name with extension. If you specify more than one value, separate the values with a comma (,).

The default value is ManagedPipelineHandler.

name

Specifies the unique name of the handler mapping.

path

Required string attribute.

Specifies the file name extension or the file name with extension for which the handler mapping applies.

preCondition

Optional string attribute.

Specifies conditions under which the handler will run.

The preCondition attribute can be one or more of the following possible values. If you specify more than one value, separate the values with a comma (,).

ValueDescription
bitness32 Specify the bitness32 value when the handler is a 32-bit .dll file, and IIS should load the handler only for worker processes that run in WOW64 mode (32-bit simulation) on a 64-bit operating system.
bitness64 Specify the bitness64 value when the handler is a 64-bit .dll file, and IIS should load the handler only for worker processes that run in 64-bit mode.
integratedMode Specify the integratedMode value when the handler should respond only to requests in application pools that are configured to use the integrated request-processing pipeline.
ISAPIMode Specify the ISAPIMode value when the handler should respond only to requests in application pools that are configured to use Classic mode.
runtimeVersionv1.1 Specify the runtimeVersionv1.1 value when the handler should respond only to requests in application pools that are configured to use .NET Framework version 1.1.
runtimeVersionv2.0 Specify the runtimeVersionv2.0 value when the handler should respond only to requests in application pools that are configured to use .NET Framework version 2.0.

requireAccess

Optional enum attribute.

Specifies the type of access that a handler requires to the resource.

The requireAccess attribute can be one or more of the following possible values. If you specify more than one value, separate the values with a comma (,). The default value is Script.

ValueDescription

responseBufferLimit

Optional integer attribute.

Specifies the maximum size, in bytes, of the response buffer for a request handler.

The default value is 4194304 bytes.

scriptProcessor

Optional string attribute.

Specifies the physical path of the ISAPI extension .dll file or Common Gateway Interface (CGI) .exe file that processes the request.

The scriptProcessor attribute is required only for script map handler mappings. When you map a handler to an ISAPI extension, you must specify ISAPIModule for the modules attribute. When you map a handler to a CGI file, you must specify CGIModule for the modules attribute.
