File serving

In file serving, web applications can serve static file types, such as HTML. File-serving attributes are used by the servlet that implements file-serving behavior.

The file-serving behavior is implemented by setting the fileservingenabled property to true when configuring the web module.

Example attributes:

bufferSize

Sets buffer size used for serving static files.

extendedDocumentRoot

Enables you to configure an application with one or more directory paths from which we can serve static files and Java ServerPages (JSP) files. We can use this attribute when an application requires access to files that exist outside of the application WAR directory. For example, if several applications require access to a set of common files, we can place the common files in a directory to which we can link each application as an extended document root directory.

Use this attribute in addition to the contextRoot attribute.

We can also use this attribute to define a WebSphere variable on multiple nodes to the appropriate directory.

Example:

<fileServingEnabled="true">

<fileServingAttributes xmi:id="FileServingAttribute_1" name="extendedDocumentRoot"
   value="${MY_CUSTOM_VARIABLE}"/>

where MY_CUSTOM_VARIABLE is the WebSphere variable to define on multiple nodes.

For more information, see JSP engine configuration parameters.

file.serving.patterns.allow

Specifies that only files matching the specified pattern are served.

file.serving.patterns.deny

Specifies that files that match the specified file pattern are denied
