![]() Match, the request will be forwarded to Tomcat for resolution. If ForwardDirectories is set to true and Apache doesn't find any files that Options specifies Indexes for that directory) or a 403 Forbidden response (ifĭirective Options doesn't specify Indexes for that directory). If ForwardDirectories is set to false (default) and Apache doesn't find anyįiles that match, Apache will serve the content of the directory (if directive Local file that matches (this is done by stat-ing the file). When DirectoryIndex is configured, Apache will create sub-requests forĮach of the local-url's specified in the directive, to determine if there is a As such mod_dir should be available to Apache, JkOptions ForwardDirectories is used in conjunction with DirectoryIndexĭirective of Apache. JkOptions CollapseSlashesNone is deprecated as of 1.2.44 and will be JkOptions CollapseSlashesUnmount is deprecated as of 1.2.44 and will be JkOptions CollapseSlashesAll is deprecated as of 1.2.44 and will be URL manipulation by mod_rewrite and with URL encoded session ids. Will be partially reencoded after processing inside Apache andīefore forwarding to Tomcat. Using JkOptions ForwardURIProxy, the forwarded URI Options(vhost) = plus_options(global) - minus_options(global) + plus_options(vhost) - minus_options(vhost) Options that support enabling (plus options) and disabling (minus options), ![]() You should leave this at it's default value, unless you have a very goodĪll options are inherited from the global server to virtual hosts. You can turn the default off by switching on one of the other two options. It was "ForwardURICompatUnparsed" in version 1.2.23 and The default value is "ForwardURIProxy" since version 1.2.24. The four following options +ForwardURIxxx are mutually exclusive.Įxactly one of them is required, a negative sign prefix is not allowed with them. Without any leading signs, options will be enabled. The directive JkOptions allow you to set many forwarding options which will enable (+) We will cover these two cases in the advanced sections. Or when they want multiple developers to work on the same web server Things are even more complex when the user wants to set a configuration that uses virtual hosts, ![]() Usually based on some pattern in the request URL, and to where to direct these requests. The adaptor on the other hand needs to know what requests it is going to serve, If so it needs to let the adaptor take the request and handle it. When a request arrives, it needs to check and see if a certain request belongs to a servlet, Load the servlet container adaptor library and initialise it (prior to serving requests). Now the web server needs also to perform the following: Requests by providing the necessary content.Īdding a servlet container may somewhat change this behaviour. When these requests arrive the server does whatever is needed to serve the In a nutshell a web server is waiting for client HTTP requests. This document was originally part of Tomcat: A Minimalistic User's Guide written by Gal Shachor,īut has been split off for organisational reasons. It couldĪlso occur when using the Apache Alias directive with a Tomcat Host's appBase or Overlaps with a Tomcat Host's appBase or the docBase of any Context. This could occur if the Apache DocumentRoot Not able to serve inappropriate content such as the contents of the WEB-INFĭirectory or JSP source code. The same file system location then care must be taken to ensure that Apache is Warning: If Apache and Tomcat are configured to serve content from To learn how to setup the working entities between your web server and Tomcat Engines.įor more detailed configuration information consult the Reference Guide for You can use the connection module mod_jk with any version of Apache starting with 1.3 and any version You can adjust the "keepAlive" parameter to keep connections around for longer and this should speed everything up.This document explains how to connect Tomcat to the popular open source web server, Apache HTTP Server. With NIO, each thread can serve any number of connections, switching back and forth but retaining the connection so you don't need to do all the usual handshaking which is especially time-consuming with HTTPS but even an issue with HTTP. The defaults are maxConnections=10,000 and maxThreads=200. If you're using NIO then actually "maxConnections=1000" and "maxThreads=10" might even be reasonable. If you're using BIO then I believe they should be more or less the same. BIO will be HTTP/1.1 or 11.Http11Protocol.(And BIO has been completely thrown out of 8.5.0 and later versions.) You set this using the protocol parameter in the server.xml file. Tomcat 7 is BIO by default, although consensus seems to be "don't use BIO because NIO is better in every way". NIO – non-blocking I/O (many more connections than threads).BIO – blocking I/O (one thread per connection).
