Hi,

why is robots.txt not the obvious answer here? The companion

specification[1] has a "User-agent: webproxy" for this specific case:

### Web proxies

Gemini bots which fetch content in order to translate said content into

HTML and publicly serve the result over HTTP(S) (in order to make

Geminispace accessible from within a standard web browser) should respect

robots.txt directives aimed at a User-agent of "webproxy".

So this should suffice:

```

User-agent: webproxy

Disallow: /

```

Regards,

Johann

I must admit, I'm woefully lacking skill or background with robots.txt. Itseems like it could be a great answer.

A few questions to help me educate myself:

1. How often should that file be referenced by the proxy? It feels like ananswer might be, to check that URL before every request, but that goes inthe direction of some of the negative feedback about the favicon. One useraction -

one gemini request and more. 2. Is 'webproxy' a standard reference to any proxy, or is that somethingleft to us to decide? 3. Are there globbing-like syntax rules for the Disallow field? 4. I'm assuming there could be multiple rules that need to be mixed. Isthere a standard algorithm for that process? E.g.:User-agent: webproxyDisallow: /aAllow: /a/bDisallow: /a/b/c

Again - it seems like this could work out really well.

Thanks for helping me learn a bit more!-------------- next part --------------An HTML attachment was scrubbed...URL: <https://lists.orbitalfox.eu/archives/gemini/attachments/20210221/efe2188f/attachment.htm>
