Within this directory there are a variety

+etc/httpd/conf/access.conf
+conf
+
+This file has two major functions.
+For the Apache web server, it defines a global
+access configuration which defines what server options (Indexes", "Includes",
+"FollowSymLinks", "ExecCGI", or "MultiViews") are associated
+with specific directories ("/", "/home/httpd/html", "/home/httpd/cgi-bin",
+and "/usr/doc"). For the LON-CAPA network server and perl module
+handlers, it defines machine specific settings (lonHostID, lonRole,
+lonAdmEMail, lonDefDomain, lonLoadLim, lonExpire, and lonReceipt)
+and internal machine settings for specific directories, socket ports,
+and browser detection logic.
+
+
+configure

+
+
+etc/httpd/conf/srm.conf
+static conf
+
+
+This file configures the "name space" of the Apache web server.
+srm.conf
+defines when specific perl modules should be called to handle a given
+request. This definition is a function of both the name of the perl module,
+and a specific regular expression associated with the URL, such as
+"^/res/.*\.page".
+
+
+
+
+
+etc/httpd/conf/startup.pl
+static conf
+
+This file provides initializations for perl handlers. It adjusts what
+the module path space is (so as to include /home/httpd/lib/perl/Apache) as

+home/httpd/perl/lond
+script
+
+This is a remote command interpreter on a TCP LON-CAPA network layer.
+It accepts and processes incoming requests from other LON-CAPA machines
+on the network. lond's functionality is self-contained in the sense
+that it does not reference (import, require, use) any other file
+described in this document. There are only 15 subroutines in this
+script, however the make_new_child subroutine is quite
+complex since it parses and responds about 29 different types of
+network requests (i.e. enc, ping, pong, ekey, load, auth, passwd,
+makeuser, home, update, unsub, sub, log, put, rolesput, get, eget,
+del, keys, dump, store, restore, querysend, queryreply, idput, idget,
+tmpput, tmpget, and ls).

+(This module, like loncacc.pm also authenticates with cookies.)
+lonacc.pm coordinates access to a wide range of administrative-type
+functions (e.g. roles, logout, annotations, and bookmarks) as well
+as coordinating access to educational resources.

+home/httpd/lib/perl/Apache/loncacc.pm
+handler
+
+This module provides access to an educational resource construction area.
+This module is invoked by the URL-related pattern syntax
+LocationMatch "^/priv.*" or LocationMatch "^/\~.*".
+Authentication of user identity
+is coordinated through cookies. The abbreviation "cacc" corresponds
+to "construction-space access"). If the cookie handle is invalid, then
+this module returns a forbidden status and makes appropriate log entries.
+If the cookie handle is valid, status is determined to be okay (and,
+for the "priv"-type access, the resource is delivered by the
+lonconstruct module).

+handler
+
+This perl handling module reads in the available roles available
+for a LON-CAPA user (different courses, different privileges, etc)
+and produces a form-element HTML page which allows the user to select
+which role he wishes to exercise in the LON-CAPA system. For instance,
+a user may want to select between being a student in a thermodynamics
+physics course or a teaching assistant for an introductory calculus
+class.

+This file is an interface to the lonc processes of the LON-CAPA network
+as well as set of elaborated functions for handling information necessary
+for navigating through a given cluster of LON-CAPA machines within a domain.
+There are over 40 specialized functions in this module which handle
+the reading and transmission of metadata, user information
+(ids, names, environments, roles, logs), file information (storage, reading,
+directories, extensions, replication, embedded styles and descriptors),
+educational resources (course descriptions, section names and numbers),
+url hashing (to assign roles on a url basis), and translating abbreviated
+symbols to and from more descriptive phrases or explanations.
