如何在Heroku上运行mod_deflate

Question

我们的应用程序是在Apache上运行的PHP。我正在尝试安装mod_deflate，但是我收到错误： httpd：/app/apache/conf/httpd.conf第433行的语法错误：/app/www/heroku/conf/default.conf第19行语法错误：无法加载/ app / www / heroku / ext / mod_deflate .so到服务器：/lib/libc.so.6：找不到版本`GLIBC_2.14'（/app/www/heroku/ext/mod_deflate.so要求）

有谁知道我需要做些什么才能让它发挥作用？

这是我的default.conf：

DocumentRoot "/app/www/public"

<Directory "/app/www/public">
    Options Indexes FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
</Directory>

#
# Allow more concurrent connections per dyno
#
ServerLimit 12
MaxClients 12

#
# Enable compression with mod_deflate
#
LoadModule deflate_module /app/www/heroku/ext/mod_deflate.so
<IfModule mod_deflate.c>
    # Set compression level
    DeflateCompressionLevel 6

    # Force compression for mangled headers.

    <IfModule mod_setenvif.c>
        <IfModule mod_headers.c>
            SetEnvIfNoCase ^(Accept-EncodXng|X-cept-Encoding|X{15}|~{15}|-{15})$ ^((gzip|deflate)\s*,?\s*)+|[X~-]{4,13}$ HAVE_Accept-Encoding
            RequestHeader append Accept-Encoding "gzip,deflate" env=HAVE_Accept-Encoding
        </IfModule>
    </IfModule>
