Request Parameter Rules |
Parameter names shall not be case sensitive, but parameter values shall be case sensitive. In this document, parameter names are typically shown in uppercase for typographical clarity, not as a requirement.
Parameters in a request may be specified in any order.
An OGC Web Service shall be prepared to encounter parameters that are not part of this specification. In terms of producing results per this specification, an OGC Web Service shall not require such parameters.
Parameters consisting of lists (for example, the LAYERS and STYLES in WMS GetMap) shall use the comma (",") as the separator between items in the list. Additional white space shall not be used to delimit list items. If a parameter value includes a space or comma, it shall be escaped using the URL encoding rules [IETF RFC 2396]. Individual entries in a list may be empty, as represented by two successive commas (",,").
