Basscheffers:

'''Session module implemented as C module by Bas Scheffers.''' As a bonus it also comes with a simple cookie API.

Find the latest version at [http://bas.scheffers.net/aolserver/ http://bas.scheffers.net/aolserver/].

----
Tcl API:

* ns_session exists - check if a session is already created - note that any of the below options implicitely create a session.
* ns_session [-id id] put key value - put a value in the session, overwrite existing entry with same key.
* ns_session [-id id] contains key - true (1) if key exists, false (0) otherwise
* ns_session [-id id] get key [default] - get a value from the session, returns default or empty string if invalid key.
* ns_session [-id id] delete key - delete a key
* ns_session [-id id] destroy - invalidate the session
* ns_session [-id id] keys - list all keys for this session
* ns_session list - list of all session IDs

''[[Jamie Rasmussen]] maintains a list of AOLserver modules tested against Windows[http://empoweringminds.spd.dcu.ie/openacs/aolserver_modules]. (Not recently updated - JR)''

== Standard Modules ==

AOLserver ships with the following modules:

* [[nscgi]] -- Standard CGI support for running external C programs, perl scripts etc.
* [[nscp]] -- Admin/debug support via a telnet like interface into a running server.
* [[nsdb]] -- The database interface, loads database specific drivers (below).
* [[nsext]] -- Communicates with external database drivers via proxy daemon.
* [[nslog]] -- Common log format or extended common log format access logging.
* [[nsperm]] -- Access control lists for groups/users, supports basic auth.
* [[nssock]] -- Standard [[socket driver]], used for HTTP requests.
* [[nsssl]] -- SSL [[socket driver]], links against proprietary RSA BSAFE library (not supplied).

== Database Drivers ==

AOLserver database drivers are either internal or external. Internal drivers are shared libraries that are loaded in-process with the webserver -- they provide the best performance. External drivers are shared libraries which are loaded by the AOLserver database proxy daemon [[nsext]], which communicates with the webserver process via sockets. The advantage of running the database driver external to the webserver is that it isolates buggy, non-threadsafe database access libraries. These days however this is largely unneccessary, and the external drivers are usually slower due to context switching overhead.

* [[dqd_db2]] -- Internal '''IBM DB2''' driver (unmaintained).
* [[nsberkeleydb]] -- Internal '''BerkeleyDB''' driver.
* [[nsfreetds]] -- Internal MS '''SQL Server'''/'''Sybase''' driver.
* [[nsinformix]] -- Internal '''Informix''' driver.
* [[nsingres]] -- Internal '''Ingres r3''' driver.
* [[nsibasepd]] -- External '''Interbase''' driver.
* [[nsmysql]] -- Internal '''MySQL''' driver.
* [[nsodbc]] -- Internal '''ODBC''' driver.
* [[nsoracle]] -- Internal '''Oracle''' driver.
* [[nspostgres]] -- Internal '''PostgreSQL''' driver.
* [[nssolid]] -- Internal '''Solid''' driver.
* [[nssqlite2]] -- Internal '''SQLite v2''' driver.
* [[nssqlite3]] -- Internal '''SQLite v3''' driver.
* [[nsunixodbc]] -- Internal ODBC driver which uses the '''unixODBC''' driver.

== Encryption / Security ==

* [[nsblowfish]] -- Encrypt Tcl strings with Blowfish cypher and hex encode.
* [[nsencrypt]] -- Uses OpenSSL to encrypt using the AES, Blowfish, Cast5, IDEA and DES cyphers.
* [[nsnss]] -- New SSL [[socket driver]], links against Netscape's portable runtime (NSPR) and security services (NSS) libraries.
* [[nsopenssl]] -- SSL [[socket driver]] links against OpenSSL, and also provides client connection capabilities.
* [[nspasswd]] -- CRYPT, MD5, SMD5, SHA and SSHA hashing algorithms.
* [[nssha1]] -- AOLserver module to perform SHA1 hashes.
* [[nspam]] -- Interface to Pluggable Authentication Modules (PAM).
* [[nsdigest]] -- Access control lists for groups/users (like [[nsperm]]), supports digest authentication.
* [[nsmhash]] -- Implementation of mhash library interface to hash, hmac and keygen algorithms (MD5,SHA1, ...). Available shared with nsv_*.
* [[nsmcrypt]] -- Implementation of mcrypt library interface to crypt,decrypt algorithms (blowfish, des, ...). Available shared with nsv_*.

== Virtual Hosting ==

AOLserver 2.x and 4.x have built-in support for software or name-based [[virtual hosting]], but AOLserver 3.x does not. Hardware virtual hosting (each server on its own port or IP) is supported across all three versions.

* [[nsvhr]] -- Redirecting proxy, passes virtualy hosted requests back to standalone server.
