$pool = ifx_pconnect($database, $id, $password);

$sql = "select * from tbl_blob where libelle='" . $uid . "'";
$prep = ifx_query($sql,$pool,$tbl);
$table = ifx_fetch_row($prep,"NEXT");

if (is_array($table)) {
        $bib = $table[blobe];
        header("Content-type: image/jpeg");
        $a = ifx_get_blob($bib);
        echo $a;
}

This program is OK in RH 7.0 (Apache/1.3.20, PHP4.2.3)

in RH 8.0 ( Apache/2.0.40, PHP4.2.3)
the ifx_get_blob is blocked (no response of the navigator)

It's OK if i get the blob thirst than header :

        $bib = $table[blobe];
        $a = ifx_get_blob($bib);
        header("Content-type: image/jpeg");
        echo $a;

Thanks
