Documentation

The Request Controller service provides an extension point to apply specific configuration to httpRequest mapping a defined URL pattern. It's possible to handle synchronization, transaction or cache configuration.

Resolution Order

579
The resolution order represents the order in which this component has been resolved by the Nuxeo Runtime framework.
You can influence this order by adding "require" tags in your component declaration, to make sure it is resolved after another component.

Start Order

858
The start order represents the order in which this component has been started by the Nuxeo Runtime framework.
This number is interesting to tweak if your Java component interacts with other components, and needs to be started before or after another one.
It can be changed by implementing the method "Component#getApplicationStartedOrder()" on your Java component: components are sorted according to this reference value, in increasing order.
The default value is 1000, and the repository initialization uses number 100. Negative values can also be used.

  <extension-point name="filterConfig">
  <documentation>
      Define a new filterConfig.

      -filterConfig
        - name: name of the Filter.
        - transactional: use transaction.
        - synchonize: is synchronized
        - cached: if true, add cache-control to header
        - cacheTime: cache duration.
        - private: if true, cache is private, public if false.

      -pattern: url pattern to match

      Example of a filterConfig Registration:

      <code>
		    <filterConfig name="filterName" transactional="true" synchonize="true"
		     cached="true" private="true" cachetime="3600">
		      <pattern>/nuxeo/urlPattern/.*</pattern>
		    </filterConfig>

  <extension-point name="corsConfig">
    <documentation>
      Add a CORS compliant url's pattern

      Mandatory:
       - name: name of the config
       - pattern: url pattern to match

      Optionnal:
       - allowGenericHttpRequests: If false, only valid and accepted CORS
         requests that be allowed (strict CORS filtering).
       - allowOrigin: Whitespace-separated list of origins that the CORS
         filter must allow.
       - allowSubdomains: If true the CORS filter will allow requests from any
         origin which is a subdomain origin of the allowed origins.
       - supportedMethods: List of the supported HTTP methods.
       - supportedHeaders: The names of the supported author request headers.
       - exposedHeaders: List of the response headers other than simple
         response headers that the browser should expose to the author of the
         cross-domain request through the XMLHttpRequest.getResponseHeader()
         method.
       - supportsCredentials: Indicates whether user credentials, such as
         cookies, HTTP authentication or client-side certificates, are
         supported.
       - maxAge: Indicates how long the results of a preflight request
         can be cached by the web browser, in seconds.

      Some samples:
       - Minimal contribution:
      <code>
        <corsConfig name="minimal">
          <pattern>/nuxeo/site/.*</pattern>
        </corsConfig>
      </code>

       - Contribution with default values:
      <code>
        <corsConfig name="defaults" allowGenericHttpRequests="true"
          allowOrigin="*" allowSubdomains="false" supportedMethods="GET, POST, HEAD, OPTIONS"
          supportedHeaders="*" exposedHeaders=""
          supportsCredentials="true" maxAge="-1">
          <pattern>/nuxeo/site/.*</pattern>
        </corsConfig>
      </code>

       - Other dummy contribution:
      <code>
        <corsConfig name="dummy" allowGenericHttpRequests="true"
          allowOrigin="http://example.com http://example.com:8080"
          allowSubdomains="true" supportedMethods="GET"
          supportedHeaders="Content-Type, X-Requested-With"
          exposedHeaders="X-Custom-1, X-Custom-2"
          supportsCredentials="false" maxAge="3600">
          <pattern>/nuxeo/site/.*</pattern>
        </corsConfig>
