Abstract

Various embodiments of the invention are directed to closely integrating functionality between an internet server and a WebDAV tool. Areas of specific focus in this document include delegation of duties between the internet server and the WebDAV tool, efficient management of a resource'"'"'s content-type, support for segregation of a namespace into separate virtual roots, and determinations of whether to invoke certain processing extensions to handle requests for a given HTTP verb.

means for creating a new mapping scenario that maps the specified name extension to its specified content type if the current mapping scenarios are not sufficient to map the specified name extension to its specified content type.

2. The apparatus of claim 1, wherein the means for creating a new mapping scenario comprises means for setting a content-type property for a resource that is associated with the resource name extension.

3. The apparatus of claim 1, wherein:

the means for ascertaining comprises means for determining whether a map exists for the specified content type and name extension; and

the means for creating a new mapping scenario comprises means for creating a new map for a namespace that hosts a resource specified by the WebDAV request.

4. The apparatus of claim 3, wherein the means for creating a new map for a namespace comprises means for setting a content-type property for a resource that is associated with the resource name extension.

5. The apparatus of claim 1, wherein:

the means for ascertaining comprises means for determining whether the specified resource name extension has an existing content type associated with it; and

the means for creating a new mapping scenario comprises means for creating a new entry to an existing map for that resource name extension and the specified content type, if the specified resource name extension does not have an existing content type associated with it.

6. The apparatus of claim 1, wherein:

the means for ascertaining comprises determining whether an existing map specifies a different content type than the content type that is specified for a specified resource name extension in the WebDAV request; and

the means for creating a new mapping scenario comprises means for creating a new map for an entire namespace that is associated with the WebDAV request that contains the mapping for the specified resource extension and the specified content type.

7. The apparatus of claim 6, wherein the means for creating a new mapping scenario comprises means for setting a content-type property for a resource that is associated with the resource name extension.

9. The computer readable medium of claim 8, wherein the means for creating a new mapping scenario comprises means for setting a content-type property for a resource that is associated with the resource name extension.

10. The computer readable medium of claim 8, wherein:

the means for ascertaining comprises means for determining whether a map exists for the specified content type and name extension; and

the means for creating a new mapping scenario comprises means for creating a new map for a namespace that hosts a resource specified by the WebDAV request.

11. The computer readable medium of claim 10, wherein the means for creating a new map for a namespace comprises means for setting a content-type property for a resource that is associated with the resource name extension.

12. The computer readable medium of claim 8, wherein:

the means for ascertaining comprises means for determining whether the specified resource name extension has an existing content type associated with it; and

the means for creating a new mapping scenario comprises means for creating a new entry to an existing map for that resource name extension and the specified content type, if the specified resource name extension does not have an existing content type associated with it.

13. The computer readable medium of claim 12, wherein the means for creating a new mapping scenario comprises means for setting a content-type property for a resource that is associated with the resource name extension.

12-1. The computer readable medium of claim 8, wherein:

the means for ascertaining comprises determining whether an existing map specifies a different content type than the content type that is specified for a specified resource name extension in the WebDAV request; and

the means for creating a new mapping scenario comprises means for creating a new map for an entire namespace that is associated with the WebDAV request that contains the mapping for the specified resource extension and the specified content type.

14. A Web Distributed Authoring and Versioning (WebDAV) apparatus for associating resource name extensions and content types, the apparatus comprising:

means for receiving a WebDAV PUT request that specifies a resource name extension and a content type;

means for checking a plurality of multi-purpose internet mail extension (MIME) maps to ascertain whether any of the MIME maps are adequate to map the specified resource name extension and content type contained in the WebDAV PUT request; and

means for creating at least a portion of a new MIME map if the MIME maps that are checked are found to be inadequate to map the specified resource name extension and content type contained in the WebDAV PUT request.

15. The apparatus of claim 14, wherein the means for creating at least a portion of a new MIME map comprises means for setting a content-type property for a resource that is associated with the resource name extension.

16. The apparatus of claim 14, wherein:

the means for checking comprises means for ascertaining whether a MIME map exists for the specified content type and resource name extension; and

the means for creating at least a portion of a new MIME map comprises means for creating a new MIME map for a server namespace that hosts a resource that is specified in the WebDAV PUT request.

17. The apparatus of claim 14, wherein:

the means for checking comprises means for ascertaining whether the specified resource name extension has an existing content type associated with it; and

the means for creating at least a portion of a new MIME map comprises means for creating a new entry to a MIME map for the specified resource name extension and content type if the specified resource name extension does not have an existing content type associated with it.

18. The apparatus of claim 14, wherein:

the means for checking comprises means for ascertaining whether an existing MIME map specifies a different content type than one that is specified by the PUT request for a given resource name extension; and

the means for creating at least a portion of a new MIME map comprises means for creating a new MIME map for an entire namespace that is associated with the WebDAV PUT request that contains the mapping for the specified resource extension and the specified content type.

19. A computer-readable medium having computer-executable instructions for performing a Web Distributed Authoring and Versioning (WebDAV) method for associating resource name extensions and content types comprising:

receiving a WebDAV PUT request that specifies a resource name extension and a content type;

checking a plurality of multi-purpose internet mail extension (MIME) maps to ascertain whether any of the MIME maps are adequate to map the specified resource name extension and content type contained in the WebDAV PUT request; and
