来自服务器的响应延迟超过24小时 - 是否可能？

Question

php: My question is about the project that I want to develop using LAMP (Linux, Apache, mysql, php,) and html on the server with a shared hosting.

I want a user to enter a number into the <input type="text"> on my web-page, click "get the result" and get the result (display at another page or use ajax request - whatever).

To calculate the result it takes up to 24 hours. Is it possible to write such a project so the user's browser wait up to 24 hours? Are there any limit on dialogues between user's browser and server with a shared hosting? I mean is it limited by less than 24 hours?

Should I try this project or I'd better write it using another technologies?

Answer 1

Technically, yes, you can do ajax long-polling. A request stays open as long as you need it to (consuming web server resources) until the response is generated and returned to the user. Whether it's a good idea or not... You can't really expect a user to keep a browser window open for that long. And that's just one reason.
