Issues Regarding DNS and Apache HTTP Server This page could be summarized with the statement: don't configure Apache HTTP Server in such a way that it relies on DNS resolution for parsing of the configuration files. If httpd requires DNS resolution to parse the configuration files then your server may be subject to reliability problems (ie. it might not start up), or denial and theft of service attacks (including virtual hosts able to steal hits from other virtual hosts). A Simple Example

Apache IP-based Virtual Host Support What is IP-based virtual hosting IP-based virtual hosting is a method to apply different directives based on the IP address and port a request is received on. Most commonly, this is used to serve different websites on different ports or interfaces. In many cases, name-based virtual hosts are more convenient, because they allow many virtual hosts to share a single address/port. See Name-based vs. IP-based Virtual Hosts to help you decide.

Apache httpd Tutorial: Introduction to Server Side Includes Server-side includes provide a means to add dynamic content to existing HTML documents. Introduction Related Modules Related Directives mod_include mod_cgi mod_expires Options XBitHack AddType SetOutputFilter BrowserMatchNoCase This article deals with Server Side Includes, usually called simply SSI. In this article, I'll talk about configuring your server to permit SSI, and introduce some basic SSI techniques for adding dynami

httxt2dbm - Generate dbm files for use with RewriteMap httxt2dbm is used to generate dbm files from text input, for use in RewriteMap with the dbm map type. If the output file already exists, it will not be truncated. New keys will be added and existing keys will be updated. Synopsis httxt2dbm [ -v ] [ -f DBM_TYPE ] -i SOURCE_TXT -o OUTPUT_DBM Options -v More verbose output -f DBM_TYPE Specify the DBM type to be used for the output. If not specified, will use the APR Default. Available t

httpd - Apache Hypertext Transfer Protocol Server httpd is the Apache HyperText Transfer Protocol (HTTP) server program. It is designed to be run as a standalone daemon process. When used like this it will create a pool of child processes or threads to handle requests. In general, httpd should not be invoked directly, but rather should be invoked via apachectl on Unix-based systems or as a service on Windows NT, 2000 and XP and as a console application on Windows 9x and ME. Synopsis httpd

HTTP/2 guide This is the howto guide for the HTTP/2 implementation in Apache httpd. This feature is experimental and you may expect interfaces and directives to change between releases. The HTTP/2 protocol HTTP/2 is the evolution of the world's most successful application layer protocol, HTTP. It focuses on making more efficient use of network resources. It does not change the fundamentals of HTTP, the semantics. There are still request and responses and headers and all that. So, if you a

htpasswd - Manage user files for basic authentication htpasswd is used to create and update the flat-files used to store usernames and password for basic authentication of HTTP users. If htpasswd cannot access a file, such as not being able to write to the output file or not being able to read the file in order to update it, it returns an error status and makes no changes. Resources available from the Apache HTTP server can be restricted to just the users listed in the files created by htpassw

htdigest - manage user files for digest authentication htdigest is used to create and update the flat-files used to store usernames, realm and password for digest authentication of HTTP users. Resources available from the Apache HTTP server can be restricted to just the users listed in the files created by htdigest. This manual page only lists the command line arguments. For details of the directives necessary to configure digest authentication in httpd see the Apache manual, which is part of

htdbm - Manipulate DBM password databases htdbm is used to manipulate the DBM format files used to store usernames and password for basic authentication of HTTP users via mod_authn_dbm. See the dbmmanage documentation for more information about these DBM files. Synopsis htdbm [ -TDBTYPE ] [ -i ] [ -c ] [ -m | -B | -d | -s | -p ] [ -C cost ] [ -t ] [ -v ] filename username htdbm -b [ -TDBTYPE ] [ -c ] [ -m | -B | -d | -s | -p ] [ -C cost ] [ -t ] [ -v ] filename username password htdbm -n [

htcacheclean - Clean up the disk cache htcacheclean is used to keep the size of mod_cache_disk's storage within a given size limit, or limit on inodes in use. This tool can run either manually or in daemon mode. When running in daemon mode, it sleeps in the background and checks the cache directory at regular intervals for cached content to be removed. You can stop the daemon cleanly by sending it a TERM or INT signal. When run manually, a once off check of the cache directory is made for cach
