FWIW,

something.*.example.com

something.*.example.com

something.*.example.com

something.*.example.com would never be a valid wildcard in any DNS system. A wildcard needs to be the leftmost part of the record:

https://en.m.wikipedia.org/wiki/Wildcard_DNS_record

Wildcard DNS record

A wildcard DNS record is a record in a DNS zone that will match requests for non-existent domain names. A wildcard DNS record is specified by using a * as the leftmost label (part) of a domain name, e.g. *.example.com. The exact rules for when a wildcard will match are specified in RFC 1034, but the rules are neither intuitive nor clearly specif...

Would be cool if you could define an origin without adding a DNS record.

sathoro•7/6/23, 4:08 PM

why not? you'd just need the DNS server to handle it properly

Chaika•7/6/23, 4:13 PM

I think the spec/rfc itself says that is how wildcards work, cf's blog on it and that article imply that, would have to read to be 100% sure

Chaika•7/6/23, 4:14 PM

you could make your own non-spec complaint wildcards if you wanted, but probably not likely a dns server would do that for you

Chaika•7/6/23, 4:15 PM

don't think you could make a certificate match that though without issuing one per

sadly certificates dont accept *.*.*.*.

curl -kcurl -k to the rescue!

Erisa•7/6/23, 5:34 PM

probably deep inside the SSL/TLS spec

which is not one i want to explore today

I love RFCs.

I read through RFC8460 and RFC8461 over coffee this morning to start my day on a fun note.

How does Cloudflare pages.dev update from GitHub? Does it pull from git every certain amount of seconds to check for changes?

HelixEvo•7/7/23, 12:01 PM

Ahh I see

please don't ping employees

Erisa•7/7/23, 2:18 PM

@xbdm I removed that image because it contained a private link - please don't ping employees individually for questions, you can verify the email is valid by checking its domain AND whether it passes SPF and DKIM at your mail provider.
You can also opt to email

abusereply@cloudflare.com

abusereply@cloudflare.com

yourself to inquire further

Erisa•7/7/23, 2:18 PM

There was a private Stripe Verify link in the screenshot

Erisa•7/7/23, 2:22 PM

You can reply to the email or, if you dont trust it, send a separate email to

abusereply@cloudflare.com

It should be. Remember though that Cloudflare perform CNAME flattening. It might not be possible to CNAME the root of a domain with other providers

If you create a matching Custom Hostname on the target, it will work

What about worker plugins?
Like, instead of waiting for new worker api, just let people make plugins and expose worker client id to the plugin provider. MeowHeartCloudflare

chientrm.com•7/8/23, 12:50 PM

That would make worker api marketplace a booming

Installing and using a library, the user gotta wire the api token manually

Using plugin, the worker and the plugin provider do the auth internally.

Is there any way to reset these settings that I have preset

DDvidPi I think I figured it out, sorry!

Cyb3r-Jak3•7/8/23, 6:50 PM

You want HostnameHostname not URI full.

Cyb3r-Jak3•7/8/23, 6:51 PM

URI Full wants the exact path. So https://map.xxxx/test.txthttps://map.xxxx/test.txt would not be screened

I am trying to implement email sending functionality that is described in this blog https://blog.cloudflare.com/sending-email-from-workers-with-mailchannels/. I have used the code snippet illustrated in the blog. I have also set the txt record for the domain I want to send email from as per https://community.cloudflare.com/t/introducing-mailchannels-domain-lockdown/523913. Now when I deploy the worker and test it both using browser and api testing tools (postman, rapidapi) I don't see emails delivered to the addresses I have used (mostly gmail). Can someone please help to understand what could be a potential cause?
