Hi. Assuming version 1.8.0, use the robot_functions.php file attached in this thread.

This is untested, but in the robot_funtions.php file there are two places to edit.

First, replace the following:

PHP Code:

if (PHPDIG_SESSID_REMOVE) {
    $eval = ereg_replace(PHPDIG_SESSID_VAR.'=[a-z0-9]*','',$eval);
    $eval = str_replace("&&","&",$eval);
    $eval = eregi_replace("[?][&]","?",$eval);
    $eval = eregi_replace("&$","",$eval);
} 


with the following:

PHP Code:

if (PHPDIG_SESSID_REMOVE) {
    $my_test_comma = stristr(PHPDIG_SESSID_VAR,",");
    if ($my_test_comma !== FALSE) {
        $my_test_comma_array = explode(",",PHPDIG_SESSID_VAR);
        $my_test_comma_count = count($my_test_comma_array);
        for ($i=0; $i<$my_test_comma_count; $i++) {
            $eval = ereg_replace($my_test_comma_array[$i].'=[a-z0-9]*','',$eval);
            $eval = str_replace("&amp;amp;&amp;amp;","&amp;amp;",$eval);
            $eval = str_replace("?&amp;amp;","?",$eval);
            $eval = eregi_replace("&amp;amp;$","",$eval);
        }
    }
    else {
        $eval = ereg_replace(PHPDIG_SESSID_VAR.'=[a-z0-9]*','',$eval);
        $eval = str_replace("&amp;amp;&amp;amp;","&amp;amp;",$eval);
        $eval = str_replace("?&amp;amp;","?",$eval);
        $eval = eregi_replace("&amp;amp;$","",$eval);
    }
} 


Second, replace the following:

PHP Code:

if (PHPDIG_SESSID_REMOVE) {
    $file = ereg_replace(PHPDIG_SESSID_VAR.'=[a-z0-9]*','',$file);
    $file = str_replace("&&","&",$file);
    $file = eregi_replace("[?][&]","?",$file);
    $file = eregi_replace("&$","",$file);
} 


with the following:

PHP Code:

if (PHPDIG_SESSID_REMOVE) {
    $my_test_comma = stristr(PHPDIG_SESSID_VAR,",");
    if ($my_test_comma !== FALSE) {
        $my_test_comma_array = explode(",",PHPDIG_SESSID_VAR);
        $my_test_comma_count = count($my_test_comma_array);
        for ($i=0; $i<$my_test_comma_count; $i++) {
            $file = ereg_replace($my_test_comma_array[$i].'=[a-z0-9]*','',$file);
            $file = str_replace("&amp;amp;&amp;amp;","&amp;amp;",$file);
            $file = str_replace("?&amp;amp;","?",$file);
            $file = eregi_replace("&amp;amp;$","",$file);
        }
    }
    else {
        $file = ereg_replace(PHPDIG_SESSID_VAR.'=[a-z0-9]*','',$file);
        $file = str_replace("&amp;amp;&amp;amp;","&amp;amp;",$file);
        $file = str_replace("?&amp;amp;","?",$file);
        $file = eregi_replace("&amp;amp;$","",$file);
    }
} 


Then use define('PHPDIG_SESSID_VAR','ID1,ID2,ID3'); in the config.php file, separating each session ID by a comma if there is more than one.

Of course, you could define such a function to avoid the repeat in code. In any case, remember to remove any "word" wrapping in the above code.
