Example 26 with HttpServletRequestWrapper

use of javax.servlet.http.HttpServletRequestWrapper in project ddf by codice.

the class SparkServlet method service.

    final String relativePath = getRelativePath(req, filterPath);

Example 27 with HttpServletRequestWrapper

use of javax.servlet.http.HttpServletRequestWrapper in project sling by apache.

the class SlingServlet method service.

/**
     * If Sling has already been started, the request is forwarded to the
     * started Sling framework. Otherwise the Sling framework is started unless
     * there were too many startup failures.
     * <p>
     * If the request is not forwarded to Sling, this method returns a 404/NOT
     * FOUND if the startup failure counter has exceeded or 503/SERVICE
     * UNAVAILABLE if the Sling framework is starting up.
     * <p>
     * If a request causes the framework to start, it is immediately terminated
     * with said response status and framework is started in a separate thread.
