Tomcat压缩不会在标头中添加内容编码：gzip [英] Tomcat Compression Does Not Add a Content-Encoding: gzip in the Header

问题描述

我正在使用Tomcat压缩我的HTML内容，如下所示：

I am using Tomcat to compress my HTML content like this:

<Connector port="8080" maxHttpHeaderSize="8192"
maxProcessors="150" maxThreads="150" minSpareThreads="25"
maxSpareThreads="75" enableLookups="false" redirectPort="8443"
acceptCount="150" connectionTimeout="20000" disableUploadTimeout="true"
compression="on" compressionMinSize="128" noCompressionUserAgents="gozilla, traviata"
compressableMimeType="text/html"
URIEncoding="UTF-8" />

然而，在HTTP标题中（通过YSlow观察），我没有看到

In the HTTP header (as observed via YSlow), however, I am not seeing

Content-Encoding: gzip

导致YSlow评分较差。

resulting in a poor YSlow score.

所有我看到的是

HeadersPost
Response Headers
Server: Apache-Coyote/1.1
Content-Type:   text/html;charset=ISO-8859-1
Content-Language:   en-US
Content-Length: 5251
Date:   Sat, 14 Feb 2009 23:33:51 GMT

我正在运行apache mod_jk Tomcat配置。

I am running an apache mod_jk Tomcat configuration.

如何使用Tomcat压缩HTML内容，并在标题中添加Content-Encoding：gzip？

How do I compress HTML content with Tomcat, and also have it add "Content-Encoding: gzip" in the header?

推荐答案

看看 http://sourceforge.net/projects/pjl-comp-filter/ 。

其他自定义解决方案可能有内存泄漏。

Other custom solutions may have memory leaks.

另外，如果你是使用mod_jk然后你肯定没有使用8080连接器（它支持压缩）这些请求。

Also, if you are using mod_jk then you are certainly not using the 8080 connector (which supports compression) for those requests.
