Interestingly, SmarterTrack 11.2 seems to have a default robots.txt file. It looks like this..
Sitemap: protocol support.xyz.....net:443/Sitemap.ashx
User-agent: *
Disallow: /About/
Disallow: /App_Data/
... more below...
I dropped my own file into MRS/Main/robots.txt but it doesn't seem to be using it? Anyone figure out how to use their own robots.txt file?
