PPhatso are there docs on how to do the "dynamic redirect expressions"? I can't seem to ...

they use the ruleset engine, there's a few examples here: https://developers.cloudflare.com/rules/url-forwarding/single-redirects/examples/

Cloudflare Docs

Single Redirects — Example rules · Cloudflare Rules docs

The following sections contain example single redirect rule configurations.

Perfect, thank you.

Chaika•2/12/24, 9:23 PM

For example, if your goal was to redirect to a different subdomain or website while keeping path,

concat("https://www.example.com", http.request.uri.path)

concat("https://www.example.com", http.request.uri.path)

PhatsoOP•2/12/24, 9:24 PM

I see.

I want to redirect

/whatever/[slug]

/whatever/[slug]

/[slug]

/[slug]

i guess I need the

regex_replace

regex_replace

operator?

regex_replace(http.request.uri.path, "^/whatever/(.*)", "/${1}")

regex_replace(http.request.uri.path, "^/whatever/(.*)", "/${1}")

Chaika•2/12/24, 9:25 PM

regex is biz or higher

PhatsoOP•2/12/24, 9:25 PM

I don't see it on this page

CChaika regex is biz or higher

PhatsoOP•2/12/24, 9:25 PM

bummer

PhatsoOP•2/12/24, 9:25 PM

can I do this redirect without biz

PhatsoOP•2/12/24, 9:28 PM

maybe

concat("/", substring(http.request.uri, 9))

concat("/", substring(http.request.uri, 9))

then?

/whatever/

/whatever/

is 10 characters, so the 9th char onward should give me the rest of the path

PhatsoOP•2/12/24, 9:43 PM

Would argo give any tangible benefit to a cloudflare pages site?

Chaika•2/12/24, 9:44 PM

smart routing? It gives enterprise like inbound routing but wouldn't matter at all for routing to the origin (because the origin is cf)

PhatsoOP•2/12/24, 9:44 PM

so "a little bit", then?

Chaika•2/12/24, 9:45 PM

it depends on area. In north america I wouldn't expect much difference. in apac, maybe

Chaika•2/12/24, 9:47 PM

when a dc is near capacity CF removes customers by plan, which matters for routing. Also some locations are just not used for free/higher tier (just based off what I've seen, no exact map). Most of that routing stuff is just off anecdotal evidence "I'm in Germany and free goes to US, Pro and Ent goes to local". I'm not sure if you would get that much better routing then with Pro

Chaika•2/12/24, 9:48 PM

also just lately it seems there's been more weird routing stuff with india/germany/etc

Chaika•2/12/24, 9:49 PM

I know Argo smart routing-> origin can really be helpful though, primary point of the product

Chaika•2/12/24, 9:50 PM

you'd have to test and see if it'd be worth it just for Pages. I'd say probably not, espec if your main audience is us/eu, but I suppose that also depends on how much you value money lol

PhatsoOP•2/12/24, 10:04 PM

thanks! I appreciate the thorough response

Has anyone done a Cloudflare Redirect Rule that redirects from a subdomain to another domain with the subdomain appended? E.g

foo.example.com

foo.example.com

example.org/?id=foo

example.org/?id=foo

. Was tinkering with moving over some Page Rules but having a hard time with this bit of the puzzle

Chaika•2/12/24, 10:12 PM

usually the piece of the puzzle you need is the fact you can use a negative index with substring, ex substring(http.host, 0, -12)

arch•2/12/24, 10:14 PM

Hmmmm I was worried about that

Aarch _Hmmmm_ I was worried about that

Chaika•2/12/24, 10:19 PM

Yea something like this:

concat("https://", "chaika.me/?id=", substring(http.host, 0, -9))
// where -10  is the character count of the domain + 1 to remove the .

concat("https://", "chaika.me/?id=", substring(http.host, 0, -9))
// where -10  is the character count of the domain + 1 to remove the .

Chaika•2/12/24, 10:19 PM

Chaika•2/12/24, 10:19 PM

I was doing it same domain, if it was diff you'd use the source

arch•2/12/24, 10:20 PM

This is really helpful, thanks

Chaika•2/12/24, 10:22 PM

it'd be cool if the ruleset engine let do it more dynamically like len(cf.zone.name), but a lot of things want literal values and not fields/responses, maybe one day
