We have an application running on a tomcat 7 server, and we want the http responses that send back to the client has the keep-alive header in it. Is there a way to change some configuration, like the server.xml to make this happen? Thanks a lot!

To enable Keep-Alive, you need to explicitly request it via the HTTP header by accessing . htaccess or the main configuration file of your web server. If you turn on Keep-Alive, the HTTP response header will show Connection: keep-alive.
The Keep-Alive header is a general-type header. This header is used to hint at how the connection may be used to set a timeout and a maximum amount of requests. It can also be used to allow a single TCP connection to remain open for multiple HTTP requests/responses (default HTTP connection closed after each request).
maxPostSize. The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than or equal to 0. If not specified, this attribute is set to 2097152 (2 megabytes).
By default, Tomcat sets maxThreads to 200, which represents the maximum number of threads allowed to run at any given time. You can also specify values for the following parameters: minSpareThreads : the minimum number of threads that should be running at all times.
In HTTP/1.1, connections are assumed to be keep-alive, unless otherwise specified (by "Connection: close" header). Therefore it is usually unnecessary to explicitly set keep-alive header.
Of course, you can always add a servlet filter that sets whatever headers that you need.
