Disallow: /sr/ and Disallow: /si/ - robots.txt

[McTaggart]

Hello Mozzers - I have come across the two directives above in a robots.txt file of a website - the web dev isn't sure what they meant although he implemented robots.txt - I think just legacy stuff that nobody has analysed for years - I vaguely recall sr means search request but can't remember.

If any of you know what these directives do, then please let me know.

Have a look at your site through http://web.archive.org/. You'll be able to see what the directories were used for.

However, if there's no use for them on the current site then what's the purpose of keeping these disallows in the robots.txt?

Thanks Tomas and Mike - good advice - I have done that and found legacy stuff they've since moved away from - there is indeed no current use for the directives.

I wonder whether there's any resource on the web that lists all robots.txt directives - and interprets them - if not then perhaps it would an idea for Moz?
