Question

我想保持我的网络服务器的所有静态文件在本地压缩，并根据请求压缩或不压缩它们。

How can I pre-compress files with mod_deflate in Apache 2.x?中的答案很接近，因为实际上通过启用MultiView并使用正确的AddEncoding，我可以让Apache在我请求时从我的web服务器返回压缩的foo.tar.gz文件{ {1}}，它带有正确的foo.tar标题。

但这仅在客户端在其发送到服务器的标头中包含Content-Encoding:时才有效。 OTOH如果客户端不支持gzip编码，我的服务器告诉我，对我来说没有“可接受的”Accept-Encoding: gzip。

如果我使用foo.tar，我可以让Apache在发送之前解压缩该tarball。但是，如果我这样做，那么当我请求AddOutputFilter INFLATE tar时（或当我指定我接受gzip编码时），服务器也会解压缩内容，这显然是我不想要的。

那么当客户端不支持gzip内容编码时如何让Apache解压缩文件，而在其他情况下如何提供预压缩文件呢？

编辑：基于@covener的建议，我尝试了以下内容：

foo.tar.gz

[在这里使用Apache-2.2.22。 ]但结果实际上比前三行更糟糕：当我请求.tar.gz文件时，它现在返回而没有“Content-Encoding：”，当我请求.tar文件时，我收到了tar.gz的内容（即仍然是压缩的），无论“Accept-Encoding：”标头如何，仍然没有“Content-Encoding：”。

Answer 1

（确保您有AddEncoding gzip或x-gzip gz或它会破坏）

2.4：

<Directory /home/covener/SRC/2.4.x/built/htdocs>
  Options +MultiViews
  MultiviewsMatch Any
  FilterDeclare gzip CONTENT_SET
  FilterProvider gzip INFLATE "! req('Accept-Encoding') =~ /gzip/"
  FilterChain gzip
</Directory>

2.2：

<Directory /home/covener/SRC/2.2.x/built/htdocs>
  Options +MultiViews
  MultiviewsMatch Any
  FilterDeclare gzip CONTENT_SET
  FilterProvider gzip INFLATE req=Accept-Encoding !$gzip
  FilterChain gzip
</Directory>

Answer 2

试试这个：

DirectoryIndex "index.html.gz" "index.html"

# Don't list the compressed files in directory indexes - you probably don't want to expose
# the .gz URLs to the outside. They're also misleading, since requesting them will give the
# original files rather than compressed ones.
IndexIgnore "*.html.gz" "*.css.gz"

RewriteEngine On

# Rewrite requests for .html/.css files to their .gz counterparts, if they exist.
RewriteCond "%{DOCUMENT_ROOT}%{REQUEST_FILENAME}.gz" -s
RewriteRule "^(.*)\.(html|css)$" "$1\.$2\.gz" [QSA]

# Serve compressed HTML/CSS with the correct Content-Type header.
RewriteRule "\.html\.gz$" "-" [T=text/html,E=no-gzip:1]
RewriteRule "\.css\.gz$"  "-" [T=text/css,E=no-gzip:1]

# Define a filter which decompresses the content using zcat.
# CAVEAT: This will fork a new process for every request made by a client that doesn't
# support gzip compression (most browsers do), so may not be suitable if you're running a
# very busy site.
ExtFilterDefine zcat cmd="/bin/zcat -"

<FilesMatch "\.(html|css)\.gz$">
  <If "%{HTTP:Accept-Encoding} =~ /gzip/">
    # Client supports gzip compression - pass it through.
    Header append Content-Encoding gzip
  </If>
  <Else>
    # Client doesn't support gzip compression - decompress it.
    SetOutputFilter zcat
  </Else>

  # Force proxies to cache gzipped & non-gzipped css/js files separately.
  Header append Vary Accept-Encoding
</FilesMatch>

让Apache自动解压缩文件，但仅在需要时
