A word of warning - as you probably have surmised, query string or otherwise manipulated URLs are not good for all types of application. They work just like HTTP GET queries and as such should really be limited to idempotent interactions with the server (like search queries or other peristent URLs).

There is nothing yet equivalent to a non-cacheable data submission to the server (like HTTP POST) yet. I think it would be great if there could be one, but nothing on the horizon at the moment.

So the complex URLs you can assemble in interactions with Gemini are subject to being linked to and replayed.

For example if I have a page on my site with 100 parametrised links to a gemini based guest book, every time GUS comes to visit, there could end up being 100 new entries posted!

Best wishes

Hmm.. interesting. I'm already packing data into the URL path, so

yeah, I can just put the rest of the data in there. I'll have to try

it out when I get a minute.

The protocol spec has a max URL size of 1024 bytes, but as long as the

inputs are short I think it will work.

I like the form idea and I wrote something similar for gopher a

In my case, I used URL query parameters to keep track of

previously submitted

form values. This worked because query params do not have any

special meaning

in gopher URLs. For gemini the query component is reserved, but

you could

probably accomplish the same thing using a special path component

with the

encoded fields in it.
