Can anyone help me on this one? Thanks Jason > In a dynamic installation various add-ins to Apache are stored in separate files and linked at runtime. Dynamic, DSO, or APXS installations (all the same thing) allow you to install or upgrade parts of Apache without having to re-compile everything. You can manage the modules that Apache loads from the config file (LoadModule, ActivateModule) and update modules without having to compile other modules or Apache. A static install puts everything in one big file. Any time you change any part of your web server you end up compiling all of it. (Make often skips much of the work.) I actually prefer this for my servers. I can release a new web server with mv httpd httpd.old then a copy that puts the new program in the right place followed by killing and re-starting the server. I never have to worry about module mismatches, or what if a file is missing from the module library. I am in the unusual position of wanting to maintain a large number (currently 4) web servers with the same software, so the idea of a single file upgrade is appealing to me. I am using mod_ssl and have not yet got it working DSO, but static worked the first time I tried it, and many more since. YMMV. Rick Widmer http://www.developersdesk.com
