php session ids and search engines.

[ted_chou12]

My website pages (urls) seem to have session ids included in the urls, and i know that will some how effect the search engine prefreces, or anything to the search result, I have no access to the php.ini files, so does anyone know how this problem may be solved through the use of .htaccess files?

thanks

Can anyone please tell me if adding

php_value session.use_trans_sid 0 
php_value session.use_only_cookies 1 

to the .htaccess file in my root directory will work or not? and how to check if that the session ids in the urls are disabled so that I have successfully solved the problem?

Thanks again.

You would add that to your php scripts

[ted_chou12]

but the source of that is saying this is for .htaccess.

Then, try it.

I already added it, but i dont know whether it had made any effects or not, and i dont know if it will affect my results in the search engines.

Use the HTTP headers to determine if it's a spider or not.  Just simply don't set sessions if it's a spider, or, the all around best way to handle this...use cookies instead of sessions.

This is what I wrote, please check if I had done this correctly:

<?php //determine if is searchengine or not, and destroy sessions or not
$useragent = $_SERVER['HTTP_USER_AGENT'];
$result = false;
$searchengines = array("bot", "google", "yahoo", "msn");
foreach ($searchengines as $searchengine) {
$match = "/$searchengine/i";
if (preg_match($match, $useragent)) {$result = true;}}
if ($result == true) {session_destroy();}?>

Thanks
