Hello Filip, my personal experience after testing both tomcat and apache in front of tomcat for a web application using servlet/jsp and java classes, is that the ajp protocol used by apache (written in C) and tomcat (written in java) for the servlet to handle the HTTP requests, is slowing down the performances, for something like 30% like you said. hope this helps. -Message d'origine- De: Eoin Woods [SMTP:[EMAIL PROTECTED]] Date: dimanche 22 avril 2001 20:27 À:[EMAIL PROTECTED] Objet:Re: Tomcat or WebLogic's WebServer?

I can see why you might put Apache in front of Tomcat for reliability or security reasons. Why would you put it there for performance reasons? I don't have exact figures to hand, but when we tested this recently I think we found that putting Apache in front of Tomcat slowed things down by about 30%. What is your experience with this?

RE: Forbidden access
Hi, Thanks for the reply, I have used the IP address of my machine (single IP address) to be Allowed and it works. But I don't know how to allow a group of users to access web server? especially if there is no place to specify the network mask. Hi, I build Apache_1.3.14 with mod_perl-1.25 on RedHat Linux 7.0 with DSO. Initially both server-status and server-info works fine, but some how both of these pages denied my display request.(403 Forbidden ) I have checked httpd.conf where I have Location /server-status SetHandler server-status Order deny,allow Deny from all Allow from .mydomain.com /Locatiom In the log file it simply says denied by server. Are you sure that .mydomain.com is getting resolved correctly? Try using IP. As far as I can see DNS is working fine, nslookup can resolve the machine name. Also one should avoid using domain names on production server. It's a performance hit since it turns HostnameLookups on. http://httpd.apache.org/docs/misc/perf-tuning.html#runtime Thanks for the comments.

Get User Login Name
Hi, Is there any way to obtain user login name from perl if I put .htaccess under /usr/local/apache/htdocs/restricted and put my cgi/perl script under cgi-bin with no restriction. The reason I put no restriction for cgi-bin is to avoid user to login twice so I only place restriction under htdocs/restricted directory. ( but I lost "remote_user" environmental variable). I could get "remote_user" if I put the restriction on both cgi-bin and htdocs/restricted, but user has to login twice. Thanks PC Wang

Anyway, if you're using CPAN to install (which I assume you are, because this wouldn't be a problem for you otherwise) you can just do a "force install". I'd prefer to figure out why the test is failing, because most of the real testing is done using that test. But it's difficult because I've never seen the test fail. What permission is denied? Permission to start httpd? Perhaps you could capture the httpd.conf file that's generated and try starting the server by hand using that file. It shouldn't be too tough to figure out why it's failing if you try that (though Apache's error messages often leave a lot to the imagination).

Is this a mistake? //http://perl.apache.org/guide/install
Can some one confirm if this document on the web is correct? Building Apache and mod_perl by Hand If you wish to process the httpd build separately from the mod_perl, you should use NO_HTTPD=1 option during the perl Makefile.PL stage, then configure various things by hand and proceed with building process. You shouldn't run perl Makefile before following the steps described in this section. These are the configurations you should make before the build stage, if you choose to manually build mod_perl: mod_perl's Makefile When perl Makefile.PL is executed, $APACHE_SRC/modules/perl/Makefile will be modified to enable various options (e.g. ALL_HOOKS=1). Instead of tweaking the options during the the perl Makefile.PL, you may also edit mod_perl-x.xx/src/modules/perl/Makefile before running perl Makefile.PL. This is an optional step. Configuration Add to apache_x.x.x/src/Configuration : AddModule modules/perl/libperl.a We suggest you add this entry at the end of the Configuration file if you want your callback hooks to have precedence over core handlers. Add the following to EXTRA_LIBS: EXTRA_LIBS=`perl -MExtUtils::Embed -e ldopts` Add the following to EXTRA_CFLAGS: EXTRA_CFLAGS=`perl -MExtUtils::Embed -e ccopts` mod_perl source files Return to the mod_perl directory and copy the mod_perl source files into the apache build directory: % cp -r src/modules/perl apache_x.x.x/src/modules/ % cp -r src/modules/perl ../apache_x.x.x/src/modules/ When you have done with the configuration parts, run: % perl Makefile.PL NO_HTTPD=1 DYNAMIC=1 EVERYTHING=1\ APACHE_SRC=../apache_x.x.x/src DYNAMIC Thanks, PC Wang
