Stop OLD Session IDs from Being Indexed

[tedmcdonald]

Howdy Folks

 

I have a quick question.

 

I am getting lots of hits by search engine spiders that are trying to crawl old session ids. Anything that has "osCsid" in the URL is very old. We have not used "osCsid" as part of a session id for nearly a year (we now use a custom sid tag), yet it still shows up constantly in our logs. Up until recently, we were using the old style "search engine friendly" URLs that made ? and = into /, making it look like directories.

 

Here are examples of dead URLs

 

/product_info.php/products_id/38/osCsid/7fabd0644465192d3f809470 /default.php/cPath/63/osCsid/c5e58bba032c0997cfaedb3a681c84a6

 

What I want to do is have these old URLs bounce or return a page not found, or something that will stop these dead URLs from being indexed.

 

Please help if you can.

 

Best Regards, Ted
