Limiting redirects with rewriterule/rewritecond

Post #1 of 4 (404 views)

Hi,

In my ongoing effort to reduce the number of redirects for
linuxsecurity.com, I could use a bit more help. Currently we have one
redirect to strip off any potential trailing slash as well as another
that strips out any preceding 'www'.

RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ https://%1/$1 [R=301,L]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ $1 [R=301,L]

The rest of our redirects are of the form:

RewriteRule ^/about/us /about [L,R=301]

Should I be combining each of these to also do the above with something
like:

RewriteRule ^/about/us/? https://linuxsecurity.com/about [L,R=301]

It seems like that would reduce the number of redirects by two, but I'm
unsure of what implications that would otherwise have. Maybe if I
instead performed the RewriteConds without R=301 and just rewrote the
URL itself? I'm not sure how that works.

Any ideas greatly appreciated.
Thanks,
Dave

Perhaps you can, but be careful about not creating loops, especially if
using .htaccess files.

Also, is there a specific reason why you're not using Redirect with
mod_alias instead?

Do you mean because of patterns matching itself?

I'm not as familiar with how mod_alias works, but also thought its
functionality was more limited?

Ideas for how to do the above using mod_alias would be appreciated.

Thanks,
Dave

The general idea is to use separate vhosts to redirect to https://, or
enforce a canonical hostname, first.

Then, for more specific redirects, use Redirect or RedirectMatch - you can
even specify the return code (301,302,304).
