Python的Web应用程序：如何保持状态 [英] Python web application: How to keep state

问题描述

我写了使用web.py在启动过程中加载几十MB的数据到内存中一个WSGI兼容的Web应用程序。

I wrote a WSGI compatible web application using web.py that loads a few dozen MB data into memory during startup.

它的工作原理相当不错的web.py集成的服务器。

It works quite well with the web.py integrated server.

然而，使用Apache 2 + mod_wsgi的，每一个请求重新加载数据，从根本上重新启动该程序。由于几秒钟的加载时间，这是难以承受的。

However, using Apache 2 + mod_wsgi, every single request reloads the data, essentially starting the program again. Due to the loading time of several seconds, this is unbearable.

是不是固有的mod_wsgi还是可以配置？我有什么办法？

Is it inherent to mod_wsgi or can it be configured? What are my alternatives?

推荐答案

是它固有的mod_wsgi？不，这是在HTTP

"Is it inherent to mod_wsgi?" No. It's inherent in HTTP

既然你没有张贴您的mod_wsgi的配置，这是不可能说你做错了什么。

Since you didn't post your mod_wsgi configuration, it's impossible to say what you did wrong.

我只能猜测，你没有使用daemon模式。

I can only guess that you didn't use daemon mode.

请参阅http://$c$c.google.com/p/modwsgi/wiki/ConfigurationGuidelines#Defining_Process_Groups关于守护进程模式的详细信息。

See http://code.google.com/p/modwsgi/wiki/ConfigurationGuidelines#Defining_Process_Groups for more information on daemon mode.

这可能不是最好的解决方案。它可能会更好（远远好）使用正确的数据库。如果没有实际的code的例子，更多的细节，这一切只是猜测随机

This may not be the best solution. It may be better (far, far better) to use a proper database. Without actual code examples, and more details, this is all just random guessing.
