Apache::Session HELP!
Hi, I'm in major poop.
Got a presentation soon and my just implemented, implementation of
Apache::Session is not working as per the man page.
I've set commit to 1 and tied a session to a postgres database. I then
set a field and check the table it's not there.
When I later do a fetch on it, I get a scarey error:
[error] Object does not exist in the data store at
/usr/lib/perl5/site_perl/5.6.1/Apache/Session/Store/Postgres.pm line 81

Re: Apache::Session HELP!
Your provided code looks accurate. Given that you get no errors
trying to place the session ID in the first place, it implies that the
$sessionID you are passing in your fetchSession routine is either not being
passed, being passed incorrectly or the object does not, in fact, live in
the database.
You should check what you are passing into the routine and then see
if the key for the session is in your table.

Is it possible to change the browser's address/location URL without Redirect?
Looks like my explanation is too long or too bad.
The simple idea is in page step 1, after the
form action=/step/2 method=post.../form
submitted, I want the browser show something
http://www.example.com/step/1/error, instead of
http://www.example.com/step/2,
if there is a need for user to correct the data submitted.
It might be accomplished by using one of the approaches outlined below, but
I was wondering if there's other way that can save the overhead of the
write/read or resend the data, and the re-process. Probably not much we can
do if the URL displayed in the browser's address/location bar depends only
on the action value of the form submitted, not based on the server response?

usually
require user go back to the same step, for example, to fill the form
again.
The way my old cgi script does is just generate the form with prefilled
value plus some error message indicate what's wrong. It works ok but the
browser location will show /step/($step+1) while it actually is
/step/$step.
Now that I am working it on mod-perl I thought I should be able to do
something about it. I briefly browsed the 2 mod-perl books (eagle,
cookbook), and could not found a simple solution yet (or I missed it?). I
was think using one of the folowing might work:z
1) save the request data in a temp file and redirect or http-refresh to
/step/$step?$session_id or /step/$step/error?$session_id
Remember the content is dynamic and depend on the input form data, so
simple
redirect may not work.
Looks like Apache will not post the form data when redirect with Location?
2) print a short form with hidden data and assign action=/step/$step/error
then submit right away (onload=form.submit()?)
Does anybody have a simple solution, e.g. without redirect? Is it possible
to change the URI showing in the browser's address/location bar?
I would appreciated if somebody can pointer me to the right direction.
Harry
RE: Is it possible to change the browser's address/location URL without Redirect?
One option:
If there's an erro in form 2,
Save the user's form data in some session variables
Then use a META HTTP-EQUIV=Refresh CONTENT=0; URL=/step2 tag to get the
user's browser to redirect.
Then populate the form with the data and error message you saved in his/her
session object.
There are obviously many other ways to do this... but if you're using some
sort of session data structure, this is probably the easiest way to get it
done.

mod_perl install on SGI
Greetings, I am trying to install mod_perl with apache_1.2.26 on and SGI running 6.5.16. apache was installed from the freeware.sgi.com website using their very nice installer. Unfortunately, the clean up after installation seems to remove the Makefile that is used by mod_perl's Makefile. So running install mod_perl from cpan, I get the question Please tell me wher I can find your apache src [ ../apache_x.x/src] I can't seem to give it a path that works. I know the executable is at /usr/freeware/apache, but that gives the message can't open /Makefile No such file. I've also tried using /var/inst/fw_apache which is the downloaded source file. No dice. Any suggestion would be appreciated. Thanks, Tom Keller Thomas J. Keller, Ph.D. Oregon Health Science University MMI Research Core Facility 3181 SW Sam Jackson Park Rd.

Re: Is it possible to change the browser's address/location URL without Redirect?
Hello, HZI was wondering if that network trip can be avoided. The answer is no. You might be able to use JavaScript to do it on certain browsers, but I'm reasonably sure you can't do it on recent IE and Netscape browsers. Why do you want to do this? You could use base href/ or similar if your goal is just to make links are relative to a certain root.

Re: Is it possible to change the browser's address/location URL without Redirect?
The question is not about how to make links relative to root. The purpose is to show correctly the user what the step he is at in the process. If no mistake, he would be taken to step 2, but since the data has error and he needs correct it, so I would like the browser indicating he is still in the step 1. Although it's not that important an issue. Did you mean javascript can change the URL text displayed in the (some version of) browser's address/location bar? I know it is used to display text in status. Noemally the use of Javascript to validate the data can almost eliminate the needing of such network trip, but not always.

Re: Is it possible to change the browser's address/location URL without Redirect?
It is the browser that controls the URL in the Address bar. So one has to
make another call to get the URL refreshed. If you are worry about the
speed, you may
1) return an error code in case of error
2) in Apache's httpd.conf, config that specific error to display
/step/1/error
A simply redirection does the same job.

Re: Some consideration about my Apache::SessionManager RFC
I'd mail the authors at their last known addresses saying that you propose steal^H^H^H^H take over the namespace. If you get no reply in a couple of weeks I'd guess you're safe enough to use it. Today I've mailed to the author. Also I've asked an advice to [EMAIL PROTECTED] I like your module and I like the name. I'll give it a try when I get a chance. (But don't hold your breath:). Would you like some help with the documentation? Thanks. The module is work in progress. The perldoc I've written is also temporary. The same directives can change from day to another :-) Any help, comment or criticism are welcome! - Enrico PS: currently I've added user inactivity session expiration policy and I'm working to use Apache::Session::Flex in order to customize session data storage
Re: Is it possible to change the browser's address/location URL without Redirect?
Simple redirection does not do the same job, because the /step/1/error
page is not a simple error page - I would like it to reload the same form in
step 1 with the values filled and some message indicating what's to be
correct.
Looks like the network trip (redirect/refresh) can not be avoid. Then the
session mechanism maybe better for the speed since it sends less data.

It is the browser that controls the URL in the Address bar. So one has
to
make another call to get the URL refreshed. If you are worry about the
speed, you may
1) return an error code in case of error
2) in Apache's httpd.conf, config that specific error to display
/step/1/error
A simply redirection does the same job.

Subject: Is it possible to change the browser's address/location URL

Redirect?
Looks like my explanation is too long or too bad.
The simple idea is in page step 1, after the
form action=/step/2 method=post.../form
submitted, I want the browser show something
http://www.example.com/step/1/error, instead of
http://www.example.com/step/2,
if there is a need for user to correct the data submitted.
It might be accomplished by using one of the approaches outlined below,
but
I was wondering if there's other way that can save the overhead of the
write/read or resend the data, and the re-process. Probably not much we
can
do if the URL displayed in the browser's address/location bar depends
only
on the action value of the form submitted, not based on the server
response?

Subject: Can I change the browser's address/location?
Suppose I have a generic content handler to handle requst
/step/1, /step/2, ..., /step/n
Location /step
SetHandler perl-script
PerlHandler MyHandler
/Location
#MyHandler.pm
package MyHandler;
sub handler {
my $r=shift;
my $step = substr($r-path_info(),1);
#do something before fetch the content
#fetch content: usually include a form that will assign action
/step/($step+1)
}
So if everything goes well, the user will follow through from step 1,
step
2, until fnish.
Now if in the #do something ... part, something is wrong, it will
usually
require user go back to the same step, for example, to fill the form
again.
The way my old cgi script does is just generate the form with
prefilled
value plus some error message indicate what's wrong. It works ok but
the
browser location will show /step/($step+1) while it actually is
/step/$step.
Now that I am working it on mod-perl I thought I should be able to do
something about it. I briefly browsed the 2 mod-perl books (eagle,
cookbook), and could not found a simple solution yet (or I missed
it?).
I
was think using one of the folowing might work:z
1) save the request data in a temp file and redirect or http-refresh
to
/step/$step?$session_id or /step/$step/error?$session_id
Remember the content is dynamic and depend on the input form data, so
simple
redirect may not work.
Looks like Apache will not post the form data when redirect with
Location?
2) print a short form with hidden data and assign
action=/step/$step/error
then submit right away (onload=form.submit()?)
Does anybody have a simple solution, e.g. without redirect? Is it
possible
to change the URI showing in the browser's address/location bar?
I would appreciated if somebody can pointer me to the right direction.
Harry
