  * Function    :  execute_client_body_filters
  *
  * Description :  Executes client body filters for the request that is buffered
- *                in the client_iob. Upon success moves client_iob cur pointer
- *                to the end of the processed data.
+ *                in the client_iob. The client_iob is updated with the filtered
+ *                content.
  *
  * Parameters  :
  *          1  :  csp = Current client state (buffers, headers, etc...)
  *          2  :  content_length = content length. Upon successful filtering
  *                the passed value is updated with the new content length.
  *
- * Returns     :  Pointer to the modified buffer, or
- *                NULL if filtering failed or wasn't necessary.
+ * Returns     :  1 if the content has been filterd. 0 if it hasn't.
