I understand that the [L] flag is supposed to stop any further RewriteRules being processed but I seem to add [L] as a matter of course to every RewriteRule, and this is something that is part of nearly every rule found in code snippets and examples online.
I don't really understand when you would and wouldn't want to use an [L] flag because it seems like all the RewriteRules I ever write work with or without the [L] flag.
Can somebody provide an example of a rule that needs [L] and one that shouldn't have [L]?
