Re: submit-data and chained handlers
e.g. $r-read($in,$r-header_in('Content-length'));
or $in=$r-content();
give's my handler the data, but unfotunately exclusive - so the data
don't
reaches Apache::Registry and the cgi-script.
Any suggests?
Apache::RequestNotes.

No, Apache::RequestNotes doesn't solve my problem. Please look at this:
Files *.pl
SetHandler perl-script
PerlHandler Apache::qwerty Apache::ChainBuffer Apache::Registry
Options +ExecCGI
PerlSendHeader On
/Files
Apache::Registry processes ordinary cgi-scripts, Apache::ChainBuffer buffers
the generated content and Apache::qwerty have to parse and/or modify the
whole content. All this works fine.
But Apache::qwerty also have to get at the data submitted by the browser in
POST/PUT requests. The Eagle Book discribes how to use the $r-read() or
$r-content() function to read the data from STDIN, but using one of this
functions befor the Apache::Registry handler is involved clears the data
buffer and the cgi-scripts don't run correctly. If I use one of this
functions after Apache::Registry is called, the data buffer is allready
cleared and so Apache::qwerty can't get at the data.
Apache::RequestNotes don't work because Apache::Registry expect to read the
POST/PUT-data from STDIN.
It's important that the cgi-scripts run unmodified and without any notice of
their unnaturally environment.

Re: load balancing on apache by IP CHAINING
Servlet chaining is what the Java web server will do, and it has nothing to do with load balancing (that I can think of). ipchains is the command to enable firewall/packet filter/packet masquerading capability in linux. I would suppose that it can be used to round-robin requests or something, but I don't know how to set that up.

I think any such IP based load balancing technologies are inherently unaware of the total system issues and are simply making a jugdment based on the IP level or perhaps a specific protocol on top of IP to route the next packet (or next session).

Form Submit Question and Apache::Request
I have a form to send to a content handler and wish to use the HTML tag:
SELECT name=multi_list multiple size=4
OPTION value=1One/OPTION
OPTION value=2Two/OPTION
OPTION value=3Three/OPTION
OPTION value=4Four/OPTION
OPTION value=5Five/OPTION
OPTION value=6Six/OPTION
/SELECT
I have a handler like:
###
package testform;
use Apache::Requst;
sub handler() {
my $r = Apache::Request-new(shift);
my @list = $r-param('multi_list') || undef;
# process the list
for (@list) {
# do stuff with each selected form value
...
}
...
...
}
###
For whatever reason, I dont see the multiple values that ware selected on
the form. Any reason why I cant collect multiple values from a form using
Apache::Request?

Re: submit-data and chained handlers
Apache::RequestNotes don't work because Apache::Registry expect to
read the
POST/PUT-data from STDIN.
It's important that the cgi-scripts run unmodified and without any
notice of
their unnaturally environment.
I don't think there's any way around the fact that you can only read the
content once. That means you need to read and store it for other
handlers to use, which is what Apache::RequestNotes does.
Alternatively, you could add something to your Registry script that
stuffs the parsed values into pnotes yourself after using them. If you
put that inside a block that checks for $ENV{'MOD_PERL'}, you'll still
be able to run the script safely under standard CGI.
It also looks like you're re-inventing Apache::Filter or
Apache::OutputChain. Have you tried them?

scalar context is ruining your day :(
Try this instead:
my @list = $r-param('multi_list');
