this patch, the type wasn't too important, because all filters were put on the same list. After this patch, the filter type is very important, because there are three different types of filters, and they are all treated differently, namely: CONNECTION: Filters of this type are valid for the lifetime of this connection. PROTOCOL: Filters of this type are valid for the lifetime of this request from the point of view of the client, this means that the request is valid from the time that the request is sent until the time that the response is received. CONTENT: Filters of this type are valid for the time that this content is used to satisfy a request. For simple requests, this is identical to PROTOCOL, but internal redirects and sub-requests can change the content without ending the request. It is important to realize that the three major types above are actually broken down into smaller groups in the code, to ensure that the ordering of filters is always correct. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@93688 13f79535-47bb-0310-9956-ffa450edef68
The directory structure for this level is as follows: aaa/ This directory contains modules dealing with authorization and authentication. arch/ cache/ This directory houses modules that implement file and data caching capability. dav/ This directory houses modules that implement WebDAV functionality. echo/ experimental/ In this directory we've placed some modules which we think provide some pretty interesting functionality, but which are still in the early stages of development and could evolve radically in the future. This code isn't supported officially. filters/ This directory houses modules that perform general inline data filtering. generators/ This directory houses modules that perform data generation functions. http/ This directory houses modules that basic HTTP protocol implementation. loggers/ This directory houses modules that handle logging functions. mappers/ This directory houses modules that handle URL mapping and rewriting. metadata/ This directory houses modules that deal with Header metadata. proxy/ This houses the code for the proxy module for Apache. ssl/ test/ This directory houses modules which test various components of Apache. You should not compile these into a production server. tls/ This directory houses code for OpenSSL functionality.
