#include "nsISupports.idl"

 * An interface representing a channel which will have to execute some sort of
 * program provided via its URI to compute the data it should return.
 * If a channel implements this interface, the execution of the program in
 * question will be restricted in the following ways:
 * - If the channel does not have an owner principal, the program will not be
 *   executed at all, no matter what.  This is necessary because in this
 *   circumstance we have no way to tell whether script execution is allowed at
 *   all for the originating security context of this channel. 
 * - If the channel has an owner principal, how it is executed is controlled by
 *   this interface.  However if the owner principal does not subsume the
 *   principal of the environment in which the program is to be executed the
 *   execution will be forced to happen in a sandbox.

   * Possible ways of executing the program.

   * Don't execute at all.
  const unsigned long NO_EXECUTION = 0;

   * Execute in a sandbox, no matter how the various principals involved are
   * related to each other.
  const unsigned long EXECUTE_IN_SANDBOX = 1;

   * Execute against the target environment if the principals allow it.
  const unsigned long EXECUTE_NORMAL = 2;

   * Whether and how the program represented by this channel is to be executed.
   * The default value if this property has never been set on this channel MUST
   * @throws NS_ERROR_INVALID_ARG when set to an unrecognized value.
  attribute unsigned long executionPolicy;

   * Control whether the program should be executed synchronosly when
   * the channel's AsyncOpen method is called or whether it should be
   * executed asynchronously.  In both cases, any data that the
   * channel returns will be returned asynchronously; the only thing
   * this property affects is when the program executes.
   * The default value of this property is TRUE.
   * Setting this property after asyncOpen has been called on the
   * channel has no effect.
  attribute boolean executeAsync;
