Thanks for the info Andy.
You'll have far more experience than me on this one anyway and as you say I don't have any issues just using the [L] value but when reading up on rewrite rules I came across this content indicator several times when cgi scripts were used.

Anyway as you say it doesn't seem to affect it in any way but that's most probably because I followed your advice of moving to GT hosting and that everything's so fast I wouldn't see the difference

Thanks, John
