启用数据COM pression为的Apache2 + FastCGI的设置 [英] Enabling data compression for Apache2 + FastCGI setup

问题描述

此问题被有关我在这里早期的岗位：
CSS加载问题与Android ICS 。

This Question is Related to my earlier post here: CSS loading issue with Android ICS.

在哪里我面临的问题是 CSS和JS渲染由Android ICS的默认和海豚浏览器即可。此内容是从我的服务器的后端引擎，它使用（的Apache2 + FastCGI的Python的+ ）安装服务。

Where I was facing issue with CSS and JS rendering by Android ICS's default and Dolphin browser. This content is served from my Server's Backend Engine, Which uses (Apache2 + FastCGI + Python) setup.

当搜寻可能存在的问题，我发现，问题的主要原因是，内容并不从服务器COM pressed形式发送的。

While searching for possible problems, I found that main cause for problem was, content was NOT sent in compressed form from Server.

所以样品的响应头的看起来如下：

So sample Response Header looks something as follows:

Connection  Keep-Alive
Content-Encoding    gzip
Content-Length  5997
Content-Type    text/css
Date    Sun, 29 Jul 2012 14:29:08 GMT
Keep-Alive  timeout=15, max=100
Server  Apache (Ubuntu)
Vary    Accept-Encoding

和同样如果内容是从平面文件服务。响应头看起来如下的东西。这是由所有的浏览器正确地呈现。

and If Same content is served from flat file. Response header looks something as below. Which is rendered properly by all Browsers.

Accept-Ranges   bytes
Connection  Keep-Alive
Content-Encoding    gzip
Content-Length  1430
Content-Type    text/css
Date    Sun, 29 Jul 2012 14:28:57 GMT
Etag    "a9c06-176d-4c5e693c2a6c0"
Keep-Alive  timeout=15, max=100
Last-Modified   Sat, 28 Jul 2012 16:46:59 GMT
Server  Apache (Ubuntu)
Vary    Accept-Encoding

和一些如何，Android的ICS的默认和海豚浏览器无法呈现的内容（特别是CSS，JS内容）。它的工作原理与所有其他浏览器。

and Some How, Android ICS's default and dolphin Browser are not able to render the content (Specially css, js content). It works with all other Browsers.

但本质上，没有与后端引擎的一些问题，还因为它的uncom pressed发送数据。这里看起来有一些有趣的点，在响应头：

But Essentially, there is some problem with Backend engine also because of which uncompressed data is sent. There are few Interesting points here to look, in Response header:

1. 响应头包含字段，指出内容编码gzip的


2. 但是内容长度显示Uncom $ P $的长度pssed资源的版本。

要解决我想这个问题的一些小的改动建筑学的，在我认为可能是一个问题原因的地方。
我注意到，按CGI更换FastCGI的解决我的问题并数据现在打开Com pressed格式发送。

To solve the problem I tried few small changes in Architecture, in places where I thought could be a problem cause. I noticed, replacing the fastCGI by CGI solved my Problem and data is sent in Compressed Format now.

虽然问题解决，但我绝对的要使用的FastCGI 的。所以我寻找可以解决问题的可能的配置更改。
我已经在服务器的Apache的设置做了如下安排：

Though the problem is solved but I definately want to use fastCGI. So I am looking for possible configuration changes that can solve Problem. I have done following Arrangements in Server's Apache settings:

1. 启用紧缩从可用的Apache模块模块



2. 我的 /etc/apache2/mods-enabled/deflate.conf 文件有以下文字：

<IfModule mod_deflate.c>
          # these are known to be safe with MSIE 6
          AddOutputFilterByType DEFLATE text/html text/plain text/xml
          # everything else may cause problems with MSIE 6
          AddOutputFilterByType DEFLATE text/css
          AddOutputFilterByType DEFLATE application/x-javascript application/javascript application/ecmascript
          AddOutputFilterByType DEFLATE application/rss+xml
</IfModule>

我有以下行，以使FastCGI的工作，我的脚本在的/ etc / apache2的/启用站点-/默认文件。

<Files my_script_name.py>
    SetHandler fastcgi-script 
</Files>

FastCgiServer /path_to_script/my_script_name.py -processes 4 -socket /tmp/my_script_name.sock

我试过各种配置的变化，但他们都不似乎解决我的问题。有没有办法，我很想念这里的 FastCGI的启用COM pression

Question

I tried various configuration changes But None of them seems to be solving my Problem. Is there any thing that I am missing here to Enable compression with fastCGI?

在任何帮助，这将是鸭preciated。

Any help in this will be Appreciated.

由于提前

推荐答案

最后，我能在这里找到问题的解决方案：

Finally, I was able to find the solution of problem here: http://wiki.catalystframework.org/wiki/deployment/apache_fastcgi

在这里，对于一个问题的答案：？为什么我的应用程序很慢，服务空白页，和/或unexpededly行事FAQ部分后，他们清楚地说

Here, For answer of a Question: Why is my application so slow, serving blank pages, and/or acting unexpededly? in FAQ section, they clearly say that.

的mod_fastcgi 和 mod_deflate模块下的某些版本没有很好地共存
  阿帕奇（Debian Lenny的股票套餐为例）。一种解决方法是
  不加载放气模块。另一种解决方案是构建
  和安装的mod_fastcgi的最近的快照版本（适用于发现
   http://www.fastcgi.com/dist/ ）。

mod_fastcgi and mod_deflate do not coexist well under certain versions of apache (Debian Lenny stock packages for example). A workaround is to not load the deflate module. An alternative solution is to build and install a recent snapshot version of mod_fastcgi (found at http://www.fastcgi.com/dist/).

因此​​，对岗位的建议，我更新的中的libapache2-MOD-的FastCGI 包服务器上，现在我正在逐渐用正确的响应头值的客户端COM pressed数据。

So as suggested on post, I updated libapache2-mod-fastcgi package on Server and now I am getting compressed data at client side with correct Response header values.
