TYPO3 Core

I could confirm the issue with referred redirections in different installations.

Your solution works fine for both TYPO3 LTS-branches, tested in TYPO3 6.2.18, 6.2.19 and 7.6.3.
In TYPO3 6.2.18/19 the line to be substituted is 665.

Thanks Antoine for your solution, hope it will be merged in next versions!

Yes, but the referer won't be added as GET param or as hidden input field, so the $this->referer or $_GET[referer] is at line 677/665 NULL and therefore no redirection will be done.

The required ts configuration, from https://docs.typo3.org/typo3cms/extensions/felogin/Examples/Index.html was already included:

config {
        typolinkLinkAccessRestrictedPages = PidOfLoginPage
        typolinkLinkAccessRestrictedPages_addParams = &return_url=###RETURN_URL###
}

The referrer is added to the extra hidden fields in \TYPO3\CMS\Felogin\Controller\FrontendLoginController::showLogin():

        // Check for referer redirect method. if present, save referer in form field
        if (GeneralUtility::inList($this->conf['redirectMode'], 'referer') || GeneralUtility::inList($this->conf['redirectMode'], 'refererDomains')) {
            $referer = $this->referer ? $this->referer : GeneralUtility::getIndpEnv('HTTP_REFERER');
            if ($referer) {
                $extraHiddenAr[] = '<input type="hidden" name="referer" value="' . htmlspecialchars($referer) . '" />';
                if ($this->piVars['redirectReferrer'] === 'off') {
                    $extraHiddenAr[] = '<input type="hidden" name="' . $this->prefixId . '[redirectReferrer]" value="off" />';
                }
            }
        }

Can you find the reason why this doesn't seem to happen in your installation?

I have no idea in which project the error occurred, but after 2 years it's been a bit too long now - the ticket could be closed for me...
