.htaccess RedirectMatch help

[RachelA]

I'm a complete beginner at this, I was wondering if someone could please let me know if it were possible for this url:

[site.com...]

to be forwarded to this:

[site.com...]

With the "###" being a varying number...

I've looked at many tutorials but hours later I've gotten nowhere!

Thanks in advance for any help.

Does the user get redirected to the new URL? or do you want a rewrite so the user continues to see the same URL they requested?

Both are possible, and it is very easy if the '###' part is the exact same number on both of them.

You'll need a

RewriteCond

to look at

QUERY_STRING

and a

RewriteRule

to do the actual work - but do you need a redirect or a rewrite here?

[RachelA]

Thank you so much for your quick response!

I would like the user to get redirected to the url. And yes the ### is the same number for the redirected page.

Thanks again!

You'll need

[R=301,L]

on the end of the rule, and the target URL of the redirect will need to state the protocol and hostname as well as the path and parameters.

There's quite a lot of prior example code for doing similar stuff to that. Post your best effort code back here, using the clues above, as a basis for discussion.

I really appreciate your help.. I've used a sample code as a template for this, but its structure was very different so I'm not sure if I've set it up correctly:

RewriteEngine On
RewriteCond %{REQUEST_URI} ^/subfolder/\$
RewriteCond %{QUERY_STRING} ^value=click&class=([0-9]*)$
RewriteRule ^(.*)$ [site.com...] [R=301,L]

for [site.com...] to [site.com...]

There's several 'right' ways to do it, and very many more 'wrong' ones. This will probably be sufficient:

RewriteEngine On
RewriteCond %{QUERY_STRING} [b]&?[/b]value=click&class=([0-9][b]+[/b])[b]&?[/b] 
RewriteRule ^[b]subfolder/[/b](.*)$ http://www.site.com/[b]$1[/b]?id=[b]%1[/b] [R=301,L]

Be aware that it only responds to the parameters being in a particular order. If they are in a different order in the request, the rule will fail to run.

Does the

'value=click'

parameter *have* to be present, for the redirect to be needed? You need to think that through a bit more.

I also changed it so that the

class

parameter cannot be blank. It must have one or more digits within. Is that correct for your application?

I don't know if you also need to carry over any filename path part. I did include that, above, and omitted it below:

RewriteEngine On
RewriteCond %{QUERY_STRING} [b]&?[/b]value=click&class=([0-9][b]+[/b])[b]&?[/b] 
RewriteRule ^[b]subfolder/[/b] http://www.site.com/?id=[b]%1[/b] [R=301,L]

You need to think about what happens when someone requests a subtly wrong URL. Do you want to redirect it, or make it fail as a 404 error? You will need to test what the code actually *does* with that request, and amend the code to fit what you actually need it to do.

The second code worked perfectly! I can't thank you enough for your help.. I don't know much about the script that creates the urls, but I tried entering a wrong url and it just re-directed back to my home page by itself, which is perfect for me.

Thank you so much again for taking the time out to help me, I really appreciate your time.

Take care :)

Can you redirect URLs using a Redirect 301?

Example;

[mysite.com...] needs to be redirected to a secure ssl certificate version of the site which has the address of [mysite.com...]

Would redirecting all traffic be possible by using a .htaccess redirect 301 by using code:

redirect 301 /http://www.mysite.com/https://mysite.com

and then saving the .htaccess in the ROOT folder on an Apache Server?
