Re: Apache doesn't load anymore modules after mod_perl.so
it is OK again with 1.99-08:-) Great news! I was just about to try to track it down. Thanks for the feedback from you both Gerald

Going to be upgradeing my web servers with 2.0. Most sites will work nicly. I have found that the memory resource problem doesn't excist with 2.0 when you compile with 'worker' or fully threaded. I'm running 2 processes of apache and each of htem have like 20 threaded. performce seems good with just running one apache server. didn't do any real load testing, but I'm sure 2.0 is going to blow 1.3.x away. -- Jason These days, Apache 2 has become the default version of Apache. On my site, I run a front end Apache and a back end Apache. Front end: Apache 1.x, has mod_accel module which is like mod_proxy, but downloads all the data from the backend ASAP and frees it up immediately, so that a slow modem doesn't tie up the backend Back end: Apache 1.x with mod_perl Here's my question: Is it worth upgrading to Apache 2.x for either the front end or back end? And does Apache 2.x's mod_proxy free up the backend ASAP now?

I didn't need 20meg process serving up 2K images :) and had about 20 to 30 smaller apache process doing the 'static' content serving. Yes, that's exactly what I do.

Well, there's multiple benefits of running a separate frontend and backend server: 1. As stated above, the static HTML/GIF/JPG/etc. files don't have to be served by the heavyweight mod_perl process. 2. If the backend is serving a large file, the frontend can retrieve the entire file from the backend and free it up immediately, so that a client with a slow modem will not tie up the backend for the time it takes to download. 3. If you have different sites (presumably owned by different people) on your server, all the backend servers can execute with different userids so that the backend server of one site doesn't have to be able to read the files of another site. And, everyone can change their own server configuration. We know that Apache 2 confers benefit #1 without needing a separate frontend and backend. Benefit #2 seems to be planned, but isn't here yet. ...What about benefit #3?
