USER content objects are cached with the page. USER_INT object are not. Some plugins may need to operate in both modes, depending on the way they are called, parameters they are issued, or execution path they take. The new option allows to convert the content object into a USER_INT object from USER during execution. Here is the sample code:


if ($this->cObj->getUserObjType() == tslib_cObj::OT_USER) {
  $content = 'I am running as USER object now.';
  if (!$this->conf['allowCaching']) {
    $this->cObj->convertToUSER_INT();
    return '';
  }
}
else {
  $content .= 'I am running as USER_INT right now';
}


If allowCaching option is set to 1, the content element will switch to a USER_INT execution mode.

When a redirect using the external URL is used, the 302 HTTP status code is used. The new PageTS Config option allows using different codes:

TSFE.jumpURL_HTTPStatusCode = 301
Moved Permanently
TSFE.jumpURL_HTTPStatusCode = 302
Default – moved temporarily/redirect
TSFE.jumpURL_HTTPStatusCode = 303
Other
TSFE.jumpURL_HTTPStatusCode = 307
Temporary redirect
