| <h1>Description</h1> |
| |
| <p> |
| The RequestMethodSelector allows pipeline creation to be influenced by the method of |
| the request. For example, in a Cocoon Forms environment, a <span class="codefrag">GET</span> request |
| could be forwarded to a new FlowScript function, whilst a <span class="codefrag">POST</span> could be |
| forwarded to a continuation, for example: |
| </p> |
| |
| <pre class="code"> |
| <map:match pattern="myform"> |
| <map:select type="request-method"> |
| <map:when test="GET"> |
| <map:call function="myform"/> |
| </map:when> |
| <map:when test="POST"> |
| <map:call continuation="request-param:continuation-id"/> |
| </map:when> |
| </map:select> |
| </map:match> |
| </pre> |
| |
| |
| <h1>Configuration</h1> |
| |
| |
| <h2>Sitemap component configuration example</h2> |
| <p></p> |
| <pre class="code"> |
| <map:selectors... |
| <map:selector name="request-method" |
| logger="sitemap.selector.request-method" |
| src="org.apache.cocoon.selection.RequestMethodSelector"/> |
| ... |
| </map:selectors> |
| </pre> |
| |
| <h2>Configuration</h2> |
| <p> |
| The request method selector does not require any specific configuration, other than |
| specifying a name and an implementing class, as in the example above. |
