Debian Apache Deflate mod 不工作

  • 772

我在 debian 上运行 apache 2.2.22。

我尝试在此服务器上启用放气，但无论我做什么，响应都不会放气。

以下是已启用模块的列表：

apache2ctl -M

 core_module (static)

Syntax OK

这是我的虚拟主机：

<VirtualHost 148.251.236.145:80>

  <FilesMatch "(?i)\.((?!.*(jpg|jpeg|png|gif|bmp)).*)$">

</VirtualHost>

最后是我的 .htaccess

RewriteEngine on

RewriteBase /

RewriteRule . - [E=no-gzip:1]

## Redirect to www
#
RewriteCond %{http_host} ^tren.at [nc]

RewriteRule ^(.*)$ http://www.tren.at/$1 [r=301,nc]

如果我现在尝试从该站点获取一个简单的 html 文件，它不会被压缩。php输出也会发生同样的情况：

curl --compressed -I http://www.tren.at/test.html
HTTP/1.1 200 OK
Date: Wed, 22 Apr 2015 10:37:57 GMT
Server: Apache/2.2.22 (Debian)
Last-Modified: Wed, 12 Nov 2014 10:34:38 GMT
Accept-Ranges: none
Cache-Control: max-age=7200, private, must-revalidate
Expires: Wed, 22 Apr 2015 12:37:57 GMT
Content-Length: 322
Content-Type: text/html

我已经在 php.ini 中禁用了 output_buffering 和 zlib.output_compression。

我的配置中某处有错误吗？我还能尝试什么来查找问题/解决问题？

编辑：

有趣的是，当我在配置中出现语法错误时，我得到的 500 错误被压缩了！

apache-2.2

2 个回答

  1. 我有以下内容，它有效，并且看起来与您的完全不同。如果您将配置简化为大致这样会怎样？

    SetOutputFilter DEFLATE
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript application/x-javascript application/javascript

    另外，如果可以避免这样做，Vary: Accept-Encoding请不要忘记使用。您可能还想在传入的请求标头到达您的缓存之前调整它们（如果有的话）。否则，您将获得非常垃圾的缓存命中率，因为您将为所有不同的压缩技术和所有不同的用户代理字符串缓存 40 多种不同的表示。 Vary: User-AgentAccept-Encoding

    这是我将使用反向代理来实现这一点的内容。

    # Edit incoming request header Accept-Encoding in order
# to get greater cache utilisation and less disk utilisation. Otherwise we
# end up with a lot of (potentially different) encodings; one for each unique
# Accept-Encoding header... there would be over 50; including very unusual
# ones.
#
# This pair of regular expressions implements a two-part transform which:
#  1) for any Accept-Encoding header which has gzip, makes it the only value,
#     plus adds a dummy value to remind log-observers that it has been edited.
#  2) then, it will replace any Accept-Encoding that did not mention gzip,
#     clears it out. mod_deflate only supports gzip anyway (despite the name)
#
# I was afraid that this would have to run as an 'early' handler, and perhaps
# on older versions of Apache 2.2, perhaps that would be the case; but at least
# for httpd-2.2.3-91.el5 on RHEL 5, this is not the case. I think there was
# some talk of making the caching not and early module... but I believe the
# documentation still refers to it as an early module.
#
RequestHeader edit Accept-Encoding "^(?:.*,?\s*)?\b(gzip)\b(?:,.*)?$" "$1, MASHED"
RequestHeader edit Accept-Encoding "^(?!.*\bgzip\b.*).*$" "$1"

    MASHED 主要是为了提醒我标题已被编辑。

  2. Best Answer

    罪魁祸首是重写模式中的一条规则：

    RewriteRule . - [E=no-gzip:1]

    这是我忘记的旧配置的一部分。
