Looking at that lead me IPC::SharedCache - which is almost exactly what I have decided to do - albiet Sam Tregar's implementation appears alot better. My Implentation of the template is very simple - i.e you give it a template, then ask it to sub in all the values into the tag locations, and return a scalar ref. There are a few other methods (for defining tags and their values) -p but thats it. I seem to have implemented an HTML::TemplateLite and IPC:SharedCacheLite I have learned alot and can always reuse the code in the orginals - this is after all perl Thanks again. Greg Cope

[OT] strange mod_rewrite behaviour (for Apache::Session support)
Hello,
I am in the process of implementing persistent sessions using
Apache::Session with the session_id stored in the URL and it mostly
works. In the HTML::Mason autohandler there is the following filter:
%filter
$r-pnotes("cookie") # mangle URL only if cookie is missing
|| s#\bhref\s*=\s*"(/(?!S=)[^"\s]*)"#href="/S=$session{_session_id}$1"#gi;
/%filter
... which adds the session_id to all href links, only if the browser
doesn't return any cookie.
Now in httpd.conf there is a mod_rewrite rule inspired by a recent
thread on the modperl list:
RewriteRule ^/S=([^/]+)(/.*) $2 [E=AF_SID:$1]
This removes the session_id from the URL and adds it to the AF_SID
environment variable. This works well for all absolute URLs (starting
with a /) which is puzzling because I remember reading in this thread
that this technique mandated _relative_ URLs.
The rewrite rule fails only in one case, the root URL:
http://my.site.com/S=1d2e580af1e31cf2/Sell/index.html
... is correctly converted to
http://my.site.com/Sell/index.html
... *but*
http://my.site.com/S=1d2e580af1e31cf2/
... fails with a 404 NOT FOUND error
From the rewrite log:
127.0.0.1 - - [23/Jul/2000:15:57:31 +0200] [apartia.int/sid#815769c][rid#8149464

/initial] (1) go-ahead with / [OK]
[Sun Jul 23 15:57:31 2000] [error] [client 127.0.0.1] File does not exist: /
... so after tinkering with various mod_rewrite options for a while I
changed the RewriteRule to:
RewriteRule ^/S=([^/]+)(/.*) %{DOCUMENT_ROOT}$2 [E=AF_SID:$1]
... and now everything works fine.
But I'm still not happy because I don't understand _why_ it works.
Please let me know if you have a rational explanation.
TIA

Re: Apache::ASP Error
The error is in your simple asp page on line 66. Most likely you forgot to put '$' in front of a variable. Dmitry On Sun, 23 Jul 2000, Hans Fuchs wrote: Hello, I installed Apache::ASP.

Aborting Apache startup during PerlInitHandler
Hi!
I have got a PerlInitHandler that does some config parsing etc.
I would like Apache to stop starting up and to print out some error
message ("Config Directive blabla missing" or something like that) if
an error occures during config parsing. (As it is happing when
something is wrong with the Apache Config (httpd.cfg ...))
How can this be done?

startup file
Hello, all, I'm quite noew to modperl. I've written a cgi, using cgi.pm that I am moving to modperl. The cgi is written as one main program, with a number of subroutines spread across three libraries that are required into the main program. If I list the main program in my startup file, so it is loaded on server startup, does it load the external libraries as well?

Re: ApacheCon Europe - thoughts please ?
I am considering going to the ApacheCon Europe to see what's said and put a few faces to names and meet a few people. So am I. And I'd be shipping myself in from Montreal/Toronto for it. I'm sure it will be worth the money, but I sympathise in terms of paying out of pocket for it as well, as I'd be doing the same. I'm not sure if it's "a fair reflection" of the price of having an attendee there, but that's not what it's about: It's about making money. The conference organizers have their dreams of financial security, too, and are looking for an appropriate work/risk/reward pay-off as well. I don't think you're being a scruge. It's a lot of money to be looking at -- I know. :-) History will show whether I get up the guts to write the cheque myself.

Re: Apache::Session and blessed references
On Wed, 31 May 2000, Dylan Weed wrote:
I can't seem to get Apache::Session to save the blessedness of an object.
Is this an oversight on my part, a limitation of the module, a limitation
of the database, or an intentional design decision?
Conceptually, it seems as though an objects blessing is stored in a
different place in the Perl guts than its contents. Is the problem just
that Apache::Session never saves this information to the database?
Has anyone else had occasion to do this?
An example in Perl:
# %session is a hash tied to a DB with Apache::Session 1.51
package main;
my $dog_obj = { name = 'Fido', breed = 'Mutt' };
bless ($dog_obj, 'Dog');
$dog_obj-bark();
$session{my_dog} = $dog_obj;
# The following line dies with an error:
# cannot call method bark on unblessed reference.
$session{my_dog}-bark();
package Dog;
sub bark {
my $self = shift;
print "Woof! I'm $self-{name}";
}
You know, I thought that there was a problem here when I first saw this
email, but today I simply cannot reproduce it. When I run the example
program, everything barks.
Can you still reproduce this problem, and, if so, could you please send me
a complete, working perl program as a demonstration?

Jeffrey
Re: Foo::Bar vs. Foo::Bar
Ade wrote: I have a module I've written, let's call it Foo::Bar. Well, I have several projects running under mod_perl that use this module. I add to the module from time to time, and thus newer projects will rely on a newer version of Foo::Bar. All these projects are running on the same server, in the same mod_perl environment. So there's a problem when one version of Foo::Bar gets cached and one script needs another version, but tries to use the one in memory 'cause all it knows is that it needs Foo::Bar. Take a look at Apache::PerlVINC. - Perrin
