IPFS etag missing

[JustinDrake]

This blog post highlights that the IPFS hash should be reflected in the etag header field.

I can't find this etag field on my browser. Is the IPFS hash still returned by the Cloudflare gateway? (If not it may be worth updating the blog post.)

Indeed it is no longer being sent from Cloudflare since that blog post

Cloudflare provides a way to verify what the gateway serves via an extension described here under the section "Verifying what the Gateway Serves":

Here is that extension, which appears to be Firefox only at the moment.

Oh, interesting :)

I think the proper fix here is to update the uniswap-org docs
