I put all the collected data in the URL. It works pretty well and got rid of the temp files. It event fixed the cache problem since each generated URL is unique to the data submitted. But it generates some nasty URLs (see the bottom). Luke, good points about the ability to replay a post. Temporary session files didn't have that problem at least. I suppose I could bring back a session ID just to counter replays, but I'll wait until it becomes a problem. Anyway, I'm probably not going to write something like this again. The guestbook is kind of fun (Hello K?vin and Timur!), so I'll leave it up. But I'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==;VGhlIExhZH kgb2YgdGhlIExha2UsIGhlciBhcm0gY2xhZCBpbiB0aGUgcHVyZXN0LCBzaGltbWVyaW5nIHNhb Wl0ZSwgaGVsZCBhbG9mdCBFeGNhbGlidXIgZnJvbSB0aGUgYm9zb20gb2YgdGhlIHdhdGVyIHNp Z25pZnlpbmcgYnkgRGl2aW5lIFByb3ZpZGVuY2UgdGhhdCBJLCBBcnRodXIsIHdhcyB0byBjYXJ yeSBFeGNhbGlidXIuIFRoYXQgaXMgd2h5IEkgYW0geW91ciBraW5nIQ==;?none Paul On Fri, Jul 17, 2020 at 2:59 PM Luke Emmet <luke at marmaladefoo.com> wrote: > 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.
