Persistent variables and remoting

[tom rhodes]

Hi all,

A long long time ago I seem to remember being able to have a persistent variable in a haxe remoting server. Just trying now with a static var but it's resetting every call, I've had a quick google but can't find the ancient page that showed me how to do it all those years ago ;)

Anyone remember?

Cheers,

Tom.

You should be more specific ;)

If you're using remoting over HTTP to mod_neko (or similar), then you need to use neko.Web.cacheModule to extend the life cycle of static vars across requests.

Best,

Juraj

Hey, that was it, cacheModule not available in PHP? Thanks, I'll have a refresher read now. 

btw is it just me or has the list gone quiet? Is everyone in a telegram group or something?

I would have to guess it's a seasonal thing. I also follow the nodejs group which in general is quite a bit more active than ours, but in the past few weeks there was way less movement than here FWIW.

As for PHP, you'll either have to use a few extra tricks (with in memory stores or something) or implement `php.Web` for ReactPHP (blocking on every request).

I think I'm going to have to use a session but I wanted to avoid leaving anything on the client as I don't want the bots to knwo I'm trying to see if they are human or not... 

I'll look at ReactPHP, thanks again.

Just to clarify: cacheModule persists global states across *all* requests while sessions are per-client. If you just dump data somewhere after a request is processed and read it back before processing the next, you get *roughly* the same behaviour (plus race conditions for requests processed in parallel). There's a wide range of caching solutions for PHP (beyond sessions) and I'm rather optimistic that at least one of them had an elegant solution to your particular problem ;)
