[Question] Prototype Mismatch for Base64 under RunPerl
OS: Windows2000 Apache: 1.3.27 ModPerl: 1.27_01-dev I have a script that ran perfectly well when not run under ModPerl but have recently tried to run it under modperl using the RunPerl module. It still seems to run OK, however my error log now seems to being filled with the following error messages ... Prototype mismatch: sub Apache::ROOT::MSS_2dcgi::documents_2ecgi::encode_base64 vs ($;$) at c:/NMS/Perl/lib/Exporter.pm line 57. Prototype mismatch: sub Apache::ROOT::MSS_2dcgi::documents_2ecgi::decode_base64 vs ($) at c:/NMS/Perl/lib/Exporter.pm line 57. The errors are connected with the MIME::Base64 module when it defines the external subroutine names. The relevant section of my conf file is ...

Re: Server side programming PHP Vs CGI Vs modPerl
Hello all, Thanks for all ur reponses. With all ur suggestions and comparisons, I have decided to use mod_perl and also wrote a sample program on it which worked fine. I have installed apache-1.3.27 and mod_perl-1.27. Now I tried authenticating the user, where I have to maintain separate session for each user. When I saw how to do session management in mod_perl a module called Apache::Session was told. But when I tried it, that module was missing in my mod_perl. So I want to know, whether I have to download this module separately, or what version of mod_perl will it be available? Thanks in advance, Devi
Please wait Handler
All, I was wondering if it is possible to Create a Handler that points a user at a page with an animated gif saying something like "Please wait", and then when my other handlers have finisheddisplay the page results I want from my mod perl handlers. I guess in a nutshell I'm wondering if there is a way to send HTML headers to a browser which tells it to scrap the html it has already received and display the new HTML I am passing it. If this isn't possible, can somebody point me in the direction of a 'please wait' mechanism that is possible - Is there one? Kind regards Marty

I don't know about the handlers, but I've never read of an HTTP header to do as you ask. What I do, good or not I don't know, is send the Please Wait message as a load of HTML 'div' elements with their 'display' CSS attribute set to 'hidden'. As my program works, it sends at regular intervals little bits of JavaScript to tell the client to display another DIV. This has the effect of a progress bar incrementing. When I do not know how much I have to do, I have the progress bar reverse itself once full. When the program is ready to move on, it sends some JS to redirect the client to the next URI. I've found that animated GIFs don't work in this situation since the IE client I work with needs to get the whole document before it will look for elements linked to from that document - including images and stylesheets. Hope this helps. - -- Cheers Leemailto:[EMAIL PROTECTED] $$=qw$808273788400074285838400657879847269820080698276007265677569820727$; $$=~s$(\d\d)$\$_.=chr(\$1+32)$ge;eval; -BEGIN PGP SIGNATURE- Version: 2.6 iQCVAwUAPkzzA6drfekeF/QBAQFgQwP/Sm/840HI2pD+I4jhRqoqino2P1+Cza56 OI9aA8UYutvreXkWaoaSrmGEiPMDuaLhcOHi1fAgDCZ8k33VPrhVlgZyHz97LqAG pwrS0/cOPW+55SFQjw9RmmyIc9i6b4TPGOPury0RbaHbO+RIH23Dsag4Si5uEHuX SncVZ6Adz50= =I26o -END PGP SIGNATURE-

You'll have to download Apache::Session (and probably a lot of other usefull
modules) seperatly from CPAN, http://www.cpan.org (though I prefer
http://search.cpan.org)
Or, use the CPAN-shell that comes with Perl
(as root)
% cpan
or
% perl -MCPAN -eshell

As you've read, currently Apache::Session is not shipped with mod_perl and have to be installed separately. Apache::Session is a persistence framework for session data. He not handles web sessions for you. For a transparent management you can: 1. Use an existent application server mod_perl-based that offers this capability like Apache::ASP, Ax-Kit, HTML::Mason or HTML::Embperl, etc... 2. If you prefer to write your own mod_perl modules, you can use Apache::SessionManager, a mod_perl module that helps session management of a web application by creating session object and making it available to all other handlers transparenlty (you can found it on CPAN). It is a wrapper around Apache::Session. By - Enrico

Re: Please wait Handler
Hello, MMI guess in a nutshell I'm wondering if there is a way to send HTML MMheaders to a browser which tells it to scrap the html it has already MMreceived and display the new HTML I am passing it. MM MMIf this isn't possible, can somebody point me in the direction of a MM'please wait' mechanism that is possible - Is there one? If the long-running process will finish within the usual amount of time that a browser waits before timing out, this is easy--use an HTTP Refresh header. For example: Long running operation is http://www.example.com/getresults.pl Please wait page is at http://www.example.com/pleasewait.pl Make an HTML page which does a form submit to pleasewait.pl. pleasewait.pl just displays an HTML page with an animated please wait image on it, and its headers include the following header: Refresh: 1; url=http://www.example.com/getresults.pl?args... The browser displays the HTML on that page, and then a second later (the 1 in the Refresh header, it could be longer), the browser fetches the second page. Since the HTML and animated image are already loaded, the user sees that while waiting for the second page to load. If the process runs a very long time, you are safer writing getresults.pl (in this example) to be able to kick off a long-running job in the background, and just display the status of the job. You can snarf a Refresh header in that too so that users see it constantly updated.

That's what Randal does in the article that I posted (although his puts it in a META tag). It's called client pull, and was introduced by Netscape at the same time as server push. - Perrin
Re: Please wait Handler
Last time I experimented with Server-Push, the only browser that implemented it was Netscape 4.*. Mozilla didn't and IE didn't. Which is a pity cos it's a really useful technique.

The classic answer to this problem is described by Randal in one of his Web Techniques columns: http://www.stonehenge.com/merlyn/WebTechniques/col20.html You can also try server push (with the Content-type: multipart/x-mixed-replace header), but I'm not sure how consistently today's browsers implement that. - Perrin

This looks like the output of Apache::Status.
Without further information about your configuration etc, help is hardly
possible.
Please read the mod_perl documentation at
http://perl.apache.org
and take an even closer look at
http://perl.apache.org/docs/1.0/guide/help.html#How_to_Report_Problems
