WMS Server Technology WMS Server Technology The WMS server functions using the HTTP GET method. For a full discussion of HTTP and its methods, refer to the Internet Engineering Task Force HTTP specification (www.ietf.org). HTTP GET The GET method retrieves whatever information (in the form of an entity) is identified by the Request- URI. If the Request-URI refers to a data-producing process, it is the produced data that is returned as the entity in the response and not the source text of the process, unless that text happens to be the output of the process. For the Web Map Service, the GET method is used to retrieve entire images from whatever server is being accessed. Basic Authentication 28 Usually a Web Map Service is open to the general public and needs no authentication. From time to time, a server may limit access to only authorized users. MapInfo Spatial Server allows you to access WMS servers that use HTTP Basic Authentication. When defining a WMS layer, you can add a username and password to your Connection URL. The format of the HTTP URL is: wms:http://:@ For example: wms:http://admin:admin@localhost:8008/rest/EnterpriseMapping/WMS? If you do not want to include IDs or passwords in a WMS request query, you have the option to set authentication in your client by including additional information in the HTTP header on the Web page. The following is a sample HTTP header that includes basic authorization information: GET /rest/EnterpriseMapping/WMS?SERVICE=WMS&REQUEST=GetCapabilities HTTP/1.1 Authorization: BASIC YWRtaW46aDdhU1ZEd2o3RVd5a1gzRUhNbW5Pdz09 User-Agent: Java/1.4.1 Host: 127.0.0.1:8080 Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2 Connection: keep-alive MapInfo Spatial Server 1.0
Layers and Styles The images rendered can be made of layers that are hierarchical—an image can be served that is made up of a layer that is a collection of other layers. Since WMS renders layers, the characteristics that modify the view of layers, such as styles and coordinate systems, can also be included in the layers provided. This lets you customize images because each image can act as a separate layer within the client that is accessing these images. You can find out what map layers are available from a WMS server by submitting a GetCapabilities request and examining the GetCapabilities.xml file returned in the response.
