apache+tomcat?

[Lee Zhao <Le...@netro-corp.com>]

Can someone please explain why one needs or wants to use apache in addition to tomcat? Can one just use tomcat as plain web server for serving HTML pages? Thanks in advance.

the best place to find out what to do is here:-

~/jakarta-tomcat-4.0.4/webapps/tomcat-docs/config/ajp.html
about halfway down the page under Using ApacheConfig

good luck

In particular, be aware of the difference between "fastest possible" and
"fast enough for my needs".

*Way* too many people go through the pain and agony of configuring a web
connector because they think they have to (or because people on this list
tell them they are nuts not to), when all they are running is an app with
almost no static content, or where the request rate is so low that Tomcat
standalone keeps up just fine.

My rule of thumb -- always try your app (under a representative load) on
Tomcat standalone first.  If its fast enough, then you can be done
configuring things in 15 minutes instead of 15 hours or 15 days.  If you
need the extra performance (or other features) that running behind a web
server provides, that's the time to invest in learning how to set the
connectors up.  But not until.

The main reason is performance.

Yes, Tomcat can be used standalone as an HTTP server.

However, a compiled Apache instance is faster at serving static content.
Since Tomcat's "main" job is to be a servlet container, if quick response is
an issue, it should spend its time being one, rather than serving static
content.

Of course, people's requirements are different, and Tomcat serving both
static and dynamic content is cool for many different folks depending on
their needs.

Check out the website and the mailing list archives for good bits of
information relating to this topic, it's a very popular one.

Tomcat is great at serving up dynamic content (jsp pages, servlets).
Apache is a great at serving up static content (images, html pages,
etc).

Through using mod_jk or other connectors, we can have Apache filter only
dynamic content off to Tomcat which frees up Tomcat to handle only the
stuff that matters, like JSP's and Servlets.  Let Apache handle static
content because that's what it does best.

Can one just use tomcat as plain web server for
| serving HTML pages?

Not a problem.

Thanks in advance.
