Why doesn DACS work with Apache 1.3?
Earlier versions of DACS did work with Apache 1.3 but because it did not supply the necessary hooks, patches to several Apache source files were required. These patches would have to be reviewed and possibly updated with each new release of Apache 1.3. In contrast, DACS uses a single self-contained module with Apache 2.0/2.2 and is easily built and installed. It was felt that the additional complexity for administrators to install DACS with Apache 1.3, together with the extra development time and cost, didn’t warrant supporting both servers. Release 1.3.42 is the final release of version 1.3 of the Apache HTTP Server, which has reached end of life status. There will be no more full releases of Apache HTTP Server 1.3. The Apache Software Foundation and the Apache HTTP Server Project therefore “strongly recommend that users of all earlier versions, including 1.3 family release, upgrade to to the current 2.2 version as soon as possible” *.
