CGI

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
