varnish

I have just installed varnish and its ready to serve web pages. Problem is that we are hitting open files limit. We have already set ulimit to varnish user. We want to find a file where we can write this configuration: # Maximum number of open files NFILES=131072 # Locked shared memory, default log size is 82MB + header MEMLOCK=82000 ## Configuration with VCL # # Listen on port 80, administration on localhost:6082, and forward to # one content server selected by the vcl file, based on the request. Use a # fixed-size cache file. # # Note: you must replace "example.org" with the outside IP

Using Varnish 4 , I have a set of backends that're responding with a valid Content-Length header and no Transfer-Encoding header. On the first hit from a client, rather than responding to the client with those headers, Varnish is dropping the Content-Length header and adding Transfer-Encoding: chunked to the response. (Interestingly, the payload doesn't appear to have any chunks in it - it's one contiguous payload). This causes serious problems for clients like Flash video players that are trying to do segment-size, bandwidth, etc analysis based on the Content-Length header. Their analysis

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 由 翻译 强力驱动 问题: I was speaking to a developer recently who said that no magento CE full page cache worked perfectly even with a default install. my experience of this is the same. if you use aoe_static's awesome module and phoenix's full page cache with varnish module you will get close. with the aoe_static module caching is done on a per Action basis which seems sensible to me. hole punching is done with placeholders applied via layout xml and dynamic blocks requested via a ajax call which won't be cached. cookies are set with this call as well.

My varnish version is 3.0 . My server works well while I curl the URLs, but when use varnish cache it return 503 service unavailable occasionally.

RPM包制作过程 1.1 前期工作 1）创建打包用的目录rpmbuild/{BUILD,SPECS,RPMS, SOURCES,SRPMS} 建议使用普通用户，在用户家目录中创建 2）确定好制作的对象，是源码包编译打包还只是一些库文件打包 3）编写SPEC文件 4）开始制作 1.2 RPM制作过程 1）读取并解析 filename.spec 文件 2）运行 %prep 部分来将源代码解包到一个临时目录，并应用所有的补丁程序。 3）运行 %build 部分来编译代码。 4）运行 %install 部分将代码安装到构建机器的目录中。 5）读取 %files 部分的文件列表，收集文件并创建二进制和源 RPM 文件。 6）运行 %clean 部分来除去临时构建目录。 补充说明： BUILD目录：制作车间，二进制tar.gz包的解压后存放的位置，并在此目录进行编译安装 SPECS目录：存放SPEC文件 RPMS目录：存放制作好的rpm包 SOURCES目录：存放源代码 SRPMS目录：存放编译好的二进制rpm包 BUILDROOT目录：此目录是在BUILD目录中执行完make install之后生成的目录，里面存放的是编译安装好的文件，他是./configure中―prefix指定path的根目录 1.3制作工具：rpmbuild 制作过程的几个状态 rpmbuild -bp 执行到

I want to use Varnish to cache certain pages even in the presence of cookies. There are 3 possibilities that I need to take care of: An anonymous user is viewing some page A logged in user is viewing some page with light customization. These customizations are all stored in a signed-cookie and are dynamically populated by Javascript. The vary-cookie http header is not set. A logged in user is viewing some page with
