success with Apache::Compress
Hi, after looking at mod_gzip, Apache::Gzip, Apache::GzipChain
and so on, I decided to try Apache::Compress, with some doubt that
it was "worth it"
There were a few hiccups, but it worked out great.
To test "in production" I created an alias /x to my cgi location,
and then added
Aloas /y /path/to/my/modperl/programs/
Aloas /x /path/to/my/modperl/programs/
PerlModule Apache::Filter
PerlModule Apache::RegistryNG
PerlModule Apache::RegistryBB
# original gateway
Location /y
..
SetHandler perl-script
PerlHandler Apache::RegistryBB-handler
..
/Location
# optional compressing gateway
Location /x
..
SetHandler perl-script
PerlSetVar Filter on
PerlHandler Apache::RegistryFilter Apache::Compress
..
/Location
I also changed Apache::RegistryFilter to subclass from Apache::RegistryBB
(bare bones), as that is my preferred harness.. (if you mix
Registry classes, mod_perl will not recognize the same script as
the same script and recompile it again, wasting memory).
Ok so I found one problem ..
If a client is 1.1 but does not accept gzip, then I'd get an internal
server error and a perl complaint about an invalid file handle GE.
I fixed this by changing the fallback (non compressing filter) code in
Apache::Compress to print, rather than use send_fd() .. I don't know why
this worked, but it does..
Next problem .. the zoo of browsers out there that lie about being
able to handle gzip.. I don't want to assume they all work, then have
users look at pages of gibberish, so I used mod_rewrite to conditionally
use the compressing gateway initially ONLY for two browser regexps:
(but they are by far the most popular):
RewriteCond %{HTTP_USER_AGENT} ^Mozilla/[45].*Windows.* [OR]
RewriteCond %{HTTP_USER_AGENT} ^Mozilla/[45].*Opera.*
RewriteRule ^(.*) http://back.end.server.ip/x/mysite$1 [P]
One could also, I guess, offer a new subdomain using mod_rewrite..
www.mysite.com (directed to non compressing URL)
fast.mysite.com (directed to compressing URL)
Next problem .. I had an unfortunate habit of printing
Location: blah\n\n
from my mod_perl programs which breaks under the compressing filter
chain so rather than fix this now, I used mod_rewrite RewriteRule
again to strip out my URLs that have this kind of redirect, to
point to the /y (non compressing) handler regardless.
Result: this is the good part :-)
* Since all my content is dynamic and most is HTML with fiddly stuff,
nett site outgoing bandwidth (and bill) has dropped by 2/3rds !!
* the modperl machine is now working harder.. where previously it was
delivering approx 300k/sec and was 20% cpu busy, it is now delivering
the same page count but 142kb/sec of compressed data but is 40% cpu
busy .. since it is SMP I'm guessing it takes 40% of one PIII 1ghz
to handle the load of about 140k/sec of compressed html..
* page sizes are MUCH smaller, in many/most cases...
home page -- 50k -- 12k
one 50 post forum thread -- 120k -- 22k
large html table with finnicky cell colors etc -- 87k -- 8k
* load times from the users perspective, even on a DSL line, feel
twice as fast. On a modem, for some examples above, it would feel
5x faster! my subjective feel under MSIE on just a 300mhz laptop,
but connected to a 784kbps DSL line, was that pages appear
twice as fast..
* my bandwidth bill drops by 2/3rd (would be much more but html was
not 100% of bandwidth, plus I'm conservative about switching it
on for more browsers)..
AWESOME..

RE: Odd Caching Bug
So, if I understand correctly, the database handle is getting cached more than you think it should, that's right? I was unsure where the caching was occurring. I think MaxRequestsPerChild doesn't actually cut off a connection that is kept alive (with KeepAlive). Ctrl-N in a browser could validly reuse the same connection if it is still around (if you wait too long, a keep-alive connection will be closed). This would make sense. It would seem that 'KeepAlive' keeps the 'request' open until it times out. So even though you've set up MaxRequestsPerChild to 1, each Apache child process could be serving multiple requests over a single TCP/IP connection. The answer to "where the caching is occuring" would be in Apache::DBI, which opens a single DB connection per Apache child process. - stop using Apache::DBI. - have your scripts explicitly set the date format they want every time (do not rely on "whatever format is already there"). Actually these are both not options : ) We really are not allowing developers to modify global database variables. This is the first no-no. Because it is not a strict policy somebody obviously abused it : ) With both solutions, you'll be able to leave the keep-alive enabled and use a saner MaxRequestsPerChild (like the default setting). Having "MaxRequestsPerChild 1" is harsh on resources! Understandably the configuration is not optimized but it is only in a development environment to allow for simultaneous development of modules, components and visual elements. Our production environment varies significantly in it's configuration directives. Thanks for the information though. It clarified what I was originally thinking. Thanks,

README: NAME Apache::Clean - mod_perl interface into HTML::Clean SYNOPSIS httpd.conf: Location /someplace SetHandler perl-script PerlHandler Apache::Clean PerlSetVar CleanLevel 3 /Location Apache::Clean is Filter aware, meaning that it can be used within Apache::Filter framework without modification. Just include the directives PerlModule Apache::Filter PerlSetVar Filter On and modify the PerlHandler directive accordingly... DESCRIPTION Apache::Clean uses HTML::Clean to tidy up large, messy HTML, saving bandwidth. It is particularly useful with Apache::Compress for ultimate savings. The only current configuration directive is CleanLevel, which defaults to 3. Apache::Clean will only tidy up whitespace (via $h-strip) and will not perform other options of HTML::Clean (such as browser compatibility). See the HTML::Clean manpage for details. Only documents with a content type of "text/html" are affected - all others are passed through unaltered. NOTES Verbose debugging is enabled by setting $Apache::Clean::DEBUG=1 or greater. To turn off all debug information, set your apache LogLevel directive above info level. This is alpha software, and as such has not been tested on multiple platforms or environments. It requires PERL_LOG_API=1, PERL_FILE_API=1, and maybe other hooks to function properly. FEATURES/BUGS No unknown bugs or features at this time...

I'm not exactly sure what you're asking here, but if what you're asking is "how do I rotate logfiles without doing a hard stop/start cycle?", then the answer is (from the command line...) rename the open logfiles, then send the server either a SIGHUP or a SIGUSR1, which will cause it to reopen its logfiles. SIGHUP does it "forcefully" (existing requests will aborted), while SIGUSR1 does it "gracefully", allowing each child server currently handling requests to complete the request before restarting it. If you use the 'apachectl' control script included in the apache distribution, these options correspond to 'apachectl restart' and 'apachectl graceful', respectively (although, if I remember right, the 'graceful' option wasn't added until around release 1.3.0). So, something like this is what you want to do: root# cd /usr/local/apache root# mv logs/access_log logs/access_log.21-feb-2001 root# mv logs/error_log logs/error_log.21-feb-2001 root# ./apachectl graceful At this point, new logs will be opened in the logs directory, and you can safely do whatever (gzip, archive, analyze, etc...) you want with the rotated logs.

I would recommend rebuilding it so that SDBM_File works, which is a standard module that comes with perl that Apache::ASP uses. If you don't wan't to deal with it, you can comment out instances of: use MLDBM; use SDBM_File; in ASP.pm and then set PerlSetVar NoState 1, but you won't get $Session or $Application objects. If you wanted a $Session still, you could then use Apache::Session to initialize $Session in your global.asa Script_OnStart and it would be much the same for you with $Session available to all your scripts. To test your perl for SDBM_File working, you can do something like perl -MSDBM_File -e ';' which will at least test the module for loading. If you want to rebuild your perl, I'd recommend installing it into another part of your system, so if your old perl were in /usr/... then I'd install the new perl in /usr/local/..., this way so you don't have to deal with one perl overlaying another possibly. Then you'd have to rebuild mod_perl against your new perl. -- Josh _ Joshua Chamas Chamas Enterprises Inc.

Apache::ASP Troubles
I recently installed and confiugured Linux-Mandrake 7.2 on my machine. I was trying to get Apache up and running and found that Mandrake 7.2 runs two versions of Apache 1.3.14 - the regular httpd Daemon (p80) and a httpd-perl Daemon (p8007) that is set up in httpd.conf to proxy all cgi-scripts to the httpd-perl daemon runing on port 8007. My problem is that when I try to add the Directory structure or and Files structures to set up the Apache::ASP in the httpd.conf file it does not understand the PerlHandler directive. I took out the Directory structure and placed it into the httpd-perl.conf but when I type the URL of the ASP demos on the web server all it does is print the source on the screen. I cannot get the webserver to process the ASP. Please help! Thanks, Mike Boeringa

(apache question) Working around MaxClients?
Hello, I have a high traffic website (looks like 200 GB output per month, something around 10-20 hits per day) hosted on a commercial service. The service does not limit my bandwidth usage, but they limit the number of concurrent Apache process that I can have to 41. This causes the server to delay accepting new connections during peak times. My account is a "virtual server"; what this means is that I have access to the Apache httpd.conf files and can restart the Apache daemon, but do not have the priviledge to bind a program to port 80 (so I can't put thttpd on port 80). I was thinking of serving the HTML files from Apache and the JPG files from thttpd (thttpd uses select() so it always only uses up one process, no matter how many connections it's handling) on port 8080, but there's one disadvantage: People who browse my site from behind certain firewalls can only see port 80. Does anyone know of a way to configure Apache so that it will pass port 80 traffic onto port 8080 somehow, without having access to modify the binary? It would have to do this without needing to spawn a child for every request though. Or is this impossible? Thanks, -Philip Mak ([EMAIL PROTECTED]) P.S. Is there a mailing list for general Apache questions somewhere? I can't seem to find one.
