TYPO3 Core

The forgot password email contains a hashlink that lacks scheme and host (see attachment) if

config.absRefPrefix

is set in TypoScript Setup. Therfore it's not clickable.
To generate the hashlink (in class tx_felogin_pi1 at line 346 et seq.) config.absRefPrefix and config.baseURL are analysed; config.baseURL (or plugin.tx_felogin_pi1.feloginBaseURL) are used for scheme and host in the link.
In my opinion there is no need for it - it seems to me t3lib_div::locationHeaderUrl() is a better solution.

Suggestion for improvement:
replace lines 367 to 370

$link = ($isAbsRelPrefix ? '' : $this->conf['linkPrefix']) . $this->pi_getPageLink($GLOBALS['TSFE']->id, '', array(
    $this->prefixId . '[user]' => $user['uid'],
    $this->prefixId . '[forgothash]' => $randHash
));

$link = $this->pi_getPageLink($GLOBALS['TSFE']->id, '', array(
    $this->prefixId . '[user]' => $user['uid'],
    $this->prefixId . '[forgothash]' => $randHash

$link = t3lib_div::locationHeaderUrl($link);
