Your APR does not include SSL/EVP support. Yes, but how do I enable it? --with-crypto

Make APACHE_MODULE() accept an optional prerequisite module for configure. Introduce the following configure time dependencies: mod_proxy_* (except proxy_html) require mod_proxy mod_dav_* require mod_dav mod_session_* require mod_session

We still have to pass the dependency check to APACHE_MODULE to ensure that mod_session_crypto is disabled with --enable-mods-shared=reallyall

if mod_session_crypto prereq isn't available, don't bail if the module was enabled implicitly

Enable mod_session_crypt if deps are fulfilled and mod_session is enabled

Actually check for APU_HAVE_CRYPTO at configure time. This fixes a compile error with apr 2 if crypto is disabled.

OS/2: Fix building of more modules that depend on symbols from other modules. Affected modules are: mod_heartbeat, mod_session_cookie, mod_session_crypto, mod_session_dbd and mod_disk_cache.

Fix broken mod_session_crypto build. Using -I$APR_INCLUDEDIR and -I$APU_INCLUDEDIR breaks for APR 2, because $APU_INCLUDEDIR is empty and a lonely "-I" doesn't do good for the compiler. It also breaks for VPATH builds, because then $APR_INCLUDEDIR contains two paths. Using $APR_INCLUDES $APU_INCLUDES fixes both problems and seems to be the way it is done for other modules.

Always make mod_*.h files available where they exist, modpath by modpath

Allow feature test for apr_ssl.h to succeed: Add necessary search paths temporarily to CPPFLAGS. Addition to r730717. When switching to another header, no need to again rename the ap_HAVE_APR_CRYPTO variable.

Prevent empty test statement.

Add a header check for apr_ssl.h to mod_session_crypto. The modules needs the header which is at the moment only part of the ssl-evp branch of APR.

* The previous patch did not work correctly with neither enable nor disable set. It just set all mod_session_* to 'no'.

* Require to explicitly enable mod_session_crypto since it requires the apr ssl code which is no longer present in apr trunk, but only in a separate branch.

* Fix r649054: Do the correct thing when neither enable nor disable is specfied.

* modules/session/config.m4: Have --disable-session disable mod_session_* also.

mod_session_dbd: Add a session implementation capable of storing session information in a SQL database via the dbd interface. Useful for sites where session privacy is important.

mod_session_crypto: Add a session encoding implementation capable of encrypting and decrypting sessions wherever they may be stored. Introduces a level of privacy when sessions are stored on the browser.

mod_session_cookie: Add a session implementation capable of storing session information within cookies on the browser. Useful for high volume sites where server bound sessions are too resource intensive.

mod_session: Add a generic session interface to unify the different attempts at saving persistent sessions across requests.
