TYPO3 Core

i've searched in the tslib and t3lib files that are used from index_ts.php

in the file class.t3lib_page.php the following function returns 0 if it can't find the alias in the database. and returning 0 seems to always display the mainpage.

/**
 * Returns a pagerow for the page with alias $alias
 *
 * @param    string        The alias to look up the page uid for.
 * @return    integer        Returns page uid (integer) if found, otherwise 0 (zero)
 * @see tslib_fe::checkAndSetAlias(), tslib_cObj::typoLink()
     */
    function getPageIdFromAlias($alias)    {
        $alias = strtolower($alias);
        $res = $GLOBALS['TYPO3_DB']->exec_SELECTquery('uid', 'pages', 'alias='.$GLOBALS['TYPO3_DB']->fullQuoteStr($alias, 'pages').' AND pid>=0 AND pages.deleted=0');    // "AND pid>=0" is because of versioning...
        if ($row = $GLOBALS['TYPO3_DB']->sql_fetch_assoc($res))    {
            return $row['uid'];
        }
        return 0;
    }

if i change the return value to -1 it seems like it works like it should. the typo3 internal error404 handling triggers and displays the correct error 404 page i've configured.

but the problem with incorrect http-header still remains.
it sents 302 moved an redirects to the page that should display the error.
:-(

I posted the following solution to the "english" list:

- set in localconf.php:
$TYPO3_CONF_VARS["FE"]["pageNotFound_handling"] =
'READFILE:/path/to/site/404.html';
$TYPO3_CONF_VARS["FE"]["pageNotFound_handling_statheader"] =
'HTTP/1.0 404 Not found';
(make sure you point to existing file!)
- change .htaccess from
RewriteRule .* index.php [L]
to
RewriteRule ^[^/]*\.\d+\.\d+\.html$ index.php [L]

This way 404 is returned properly. Also Google sitemaps work with this solution.

Hi,
I think that's the same issue, isn't it?
Greets, Sebastian

The bug concerning non-existant aliases is treated in the related issue, so I'll only fix the HTTP headers issue here if you agree.

Incorrect HTTP headers are fixed in CVS, to set this yourself see Dmitry's comment.
