Debug redirect rule doesn't match?

Question

I want to redirect

http://localhost/cocoon/data/vm/azure/windows-d11v2promo-standard

to

http://35.227.26.187:5000/cocoon_v1.0?subject=https://w3id.org/cocoon/data/vm/azure/windows-d11v2promo-standard

with this rule, but it doesn't work (tested locally with apache2 server)

RewriteRule ^data/([./]+)$ http://35.227.26.187:5000/cocoon_v1.0?subject=https://w3id.org/cocoon/data/$1 [L,R=308]

I have a working htaccess for https://w3id.org/cocoon/v1.0

I'd like to add redirect rules for something like

https://w3id.org/cocoon/data/vm/azure/windows-d11v2promo-standard https://w3id.org/cocoon/data/storage/azure/premiumssd-p4

Where is your .htaccess located? Can you show your complete .htaccess in question — anubhava, Oct 16 '18 at 18:13

Change your rule to this and retest:

RewriteRule ^data/.*$ http://35.227.26.187:5000/cocoon_v1.0?subject=https://w3id.org/cocoon/$0 [L,R=301,NC,NE,QSA]

In your rule's regex [./]+ only matches 1+ dot or / characters.

no, this one doesn't work. dot is `\.`, and should be $1, not $0, and I think brackets `()` are needed. – Mzq Oct 16 '18 at 20:06

No brackets needed,`$0` represents complete matching string in `RewriteRule` pattern, which will be `/data/` and we're using back-reference of same in target. – anubhava Oct 16 '18 at 21:20

Ok, must be chrome catching my redirects, [fiddling with it](https://salferrarello.com/chrome-clear-redirect-cache/) for a while to be sure. this also works. – Mzq Oct 16 '18 at 22:12

Alternative solution

root@CECS-030929:/var/www/html/cocoon/data# cat .htaccess
RewriteEngine On
RewriteRule ^(.+)$ http://35.227.26.187:5000/cocoon_v1.0?subject=https://w3id.org/cocoon/data/$1 [L,R=301,NC,NE,QSA]

But I prefer anubhava's solution, don't want to create another folder/file for just 2 lines.
