One last question

[CWebguy]

Ok, I'm going to have to pick your brain one more time ;) Thanks to all the moderators on here for all your help. Really, thank you.

My final question (of the day) is...

I can do the 301 redirect, I can do the URL rewrite, but I'm having trouble putting them together.

Current code=

RewriteCond %{QUERY_STRING} ^ca=([0-9]+)
RewriteRule ^subdir/$ http://www.example.com/subdir/%1? [R=301,L]
RewriteRule ^subdir/([0-9]+) /subdir/?ca=$1 [L]

So the rewrite rule by itself seems to work, as does the redirect, but put them together and it doesn't. Any thoughts?

Much abliged!

Oh wait, found this link [webmasterworld.com...] Will read and let you know if I have any more questions. Thanks.

The redirect should only fire for DIRECT CLIENT REQUESTS not as a result of the internal pointer being updated during a rewrite.

That is, you need to look at THE_REQUEST when evaluating whether the redirect needs to be fired.

[jdMorgan]

# Externally redirect only direct client requests for subdir+query-string URL back to static URL
RewriteCond %{THE_REQUEST} ^[A-Z]+\ /subdir/\?ca=([0-9]+)\ HTTP/
RewriteRule ^subdir/$ http://www.example.com/subdir/%1? [R=301,L]
#
# Internally rewrite requests for static URL to query string filepath
RewriteRule ^subdir/([0-9]+) /subdir/?ca=$1 [L]

sorry to say but the code isn't working.

http://www.example.com/subdir/?ca=123

still doesn't redirect even after adding the {THE_REQUEST} code.

thanks.

Is this code placed in the root folder, or the subdir folder?

Did you flush the browser cache before testing?

[CWebguy]

In the root folder, yes I did.

Final code is:

RewriteCond %{HTTP_HOST} ^example.com
RewriteRule (.*) http://www.example.com/$1 [R=301,L]
RewriteCond %{THE_REQUEST} ^[A-Z]+\ /store/?ca=([0-9]+)\ HTTP/ 
RewriteRule ^store/$ http://www.example.com/store/%1? [R=301,L] 
RewriteRule ^store/([0-9]+)$ /store/?ca=$1 [L]
#RewriteRule ^store/([0-9]+)/([a-zA-Z0-9]+)$ store/it.php?ca=$1&as=$2 [L]
#RewriteRule ^store/([0-9]+)/pg-([0-9]+)$ /store/?ca=$1&pg=$2 [L]

Trying to redirect : www.example.com/store/?ca=123 to
www.example.com/store/123 which also calls example.com/store/?ca=123 as the script. I commented out the last two lines as this isn't the focus now.

Thanks.

The literal question mark in the RewriteCond pattern needs to be escaped as shown, otherwise it will be taken as a regular-expressions quantifier meaning, "zero or one of the preceding character."

RewriteCond %{THE_REQUEST} ^[A-Z]+\ /sto[b]re/\?ca[/b]=([0-9]+)\ HTTP/
RewriteRule ^store/$ http://www.example.com/store/%1? [R=301,L]

Haha, yes! works now. Now I have to figure out how to understand it. So I'm guessing everything was correct as far as placement? (redirects before rewrites,etc.? i'm learnin')

Thanks a million.

Lines 3 and 4 MUST be moved to be the very first two lines. Specific redirect before General redirect.

Other than as noted above, I don't see why it wouldn't work. Ah, you fixed it while I was still reading.

You do have

RewriteEngine On

ahead of all of this though?

[CWebguy]

yes, of course, sorry, but not optsymlink thing. Thanks for the help.

Are you on that one?

[CWebguy]

Yes, I'll switch it, the {THE_REQUEST} before the non-www to www rewrite. Gotcha, thanks again.

[g1smd]

You need to do that for one reason.

Think what happens for a non-www request with the ?ca parameter included.

For that, there will be a double redirect: first the non-www to www redirect, and then the parameter to static redirect kicks in. That Redirection Chain is a BAD thing.

Changing the order of the code around fixes that. With the parameter redirect first, any non-www request with the ?ca parameter included is redirected to static format and the www is fixed at the same time.

That is, the following non-www to www redirect kicks in only for all other requests.
