I put all the collected data in the URL. It works pretty well and got ridof the temp files. It event fixed the cache problem since each generatedURL is unique to the data submitted. But it generates some nasty URLs (seethe bottom).
Luke, good points about the ability to replay a post. Temporary sessionfiles didn't have that problem at least. I suppose I could bring back asession ID just to counter replays, but I'll wait until it becomes aproblem.
Anyway, I'm probably not going to write something like this again. Theguestbook is kind of fun (Hello Kévin and Timur!), so I'll leave it up. ButI'll stick to things that fit better in the future.
Case in point about replays, here's an ugly URL to a pre-filled form:
gemini://pboyd.io/cgi-bin/guestbook.pl/link/S2luZyBBcnRodXI=;Q2FtZWxvdA==;VGhlIExhZHkgb2YgdGhlIExha2UsIGhlciBhcm0gY2xhZCBpbiB0aGUgcHVyZXN0LCBzaGltbWVyaW5nIHNhbWl0ZSwgaGVsZCBhbG9mdCBFeGNhbGlidXIgZnJvbSB0aGUgYm9zb20gb2YgdGhlIHdhdGVyIHNpZ25pZnlpbmcgYnkgRGl2aW5lIFByb3ZpZGVuY2UgdGhhdCBJLCBBcnRodXIsIHdhcyB0byBjYXJyeSBFeGNhbGlidXIuIFRoYXQgaXMgd2h5IEkgYW0geW91ciBraW5nIQ==;?none

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.
