This has come up a few times in this thread: you must remember that the URL does NOT include the domain name. Therefore, the above rule takes the whole URL from beginning to end and *prepends* the hostname so that in the subsequent rule (not shown above), you can also extract parts of the host name (since parts are needed for rewritten the URL). > rewriteRule ^([a-z])(.*)([0-9])\.domain\.ext(.*) www$3.domain.ext/$2_$1$4 > > Rule, > lowercase-alpha saved as $1 > plus > zero or more of everything saved as $2 > plus > 0-9 numeric saved as $3 > plus > domain.ext > plus > zero or more of anything saved as $4 > > rewrite to > www$3.domain.ext/$2_$1$4 You got it so far... > In the case of www.domain.ext/subdomain/file220110.html this would > result in a severely fractured URL I think. I was just given an example of how parts of the domain name can be extracted and put in URL path with proper rules and conditions. >> What will it do to the following HTTP requests: > > Oh wow.

Wrong: the pattern for 2nd rule requires a digit just before the first dot of host name, so rule will get skipped and URL unchanged. > > Reese > It's really important to understand how the conditions and pattern matching work, together with regexp. There may be other issues to consider when the rule is in an .htaccess (I gather you only get part of the URL path then).
