Re: Which template engine is best to create a perl site

Replacement for CGI.pm escape and unescape
Hi All, I'm running the latest mp2 with Libapreq. Is there some method to duplicate CGI.pm's escape and unescape methods? I found escape_path, but obviously that isn't the same thing. I'm trying to remove CGI.pm from all my code and these are the last 2 things I need to take care of. TIA! -Chris

Unless your templating engine is showing up pretty high on your Devel::DProf output, you're probably not going to save much. Saving 5% won't mean saving a machine for anyone except really large sites with very well-tuned machines. when i said that many people don't care about speed because of their database slowness i also meant that i wonder why people don't rethink their architecture. if the database is so slow that it makes no difference how slow your perl-code is, then there's often a possibility to optimize that (cache things, use a search engine for searches instead of the database, change replication architecture, ...) I agree, and that's where people who are seeing database activity as a bottleneck should spend their time. They can save time on their templating engine choice by choosing the one with the development features that they find most useful and not trying to figure out which one is fastest. All I'm saying is use your optimization time wisely. Good error messages and an easy API are more important than speed in a templating tool now. If the dot notation in HTML::Template::Compiled saves a developer a few hours of coding which can then be spent on database query tuning, that's probably a much bigger win than any speed difference.in templating modules. - Perrin

Re: asynchronous perl authentication!?
Hi Adam,
You are perfectly right. However, I'm in dire need of a Ajax style login.
Do you have any clue on how to go about implementing the sytem?
Adam Tistler wrote:
Even if you use AJAX, the page will still refresh because the AuthCookie
module's authentication method redirect's you back to the login page so
that the session cookie can be checked. You might be able to get around
that by overloading the authentication method using a subrequest instead
of a redirect, although I am not entirely sure that will work.
You say something about overloading the authentication method? Does that
mean I've to overload the login method? Is that a standard way?
It would help me a lot if you can tell me how to send an XML back if in
case the login fails. What I mean is the following.
sub authen_cred {
# this is the first time user is logging in
my $allow = check_user_credentials(...);
if $allow {
# generate cookie that is checked subsequently my auth_sess_cookie
...
} else {
# return a XML with http status set to HTTP_FORBIDDEN
...
}
}
Is that understandable? How do I implement the else part? If I simply say
something like...
HTTP_FORBIDDEN unless check_user_credentials(...)
I see that the browser simply displays 404 on the screen. I thought that
this implies that I can break the authen_cred - auth_sess_key flow, if in
case I can return an XML and further using AJAX, can display a error message
when login fails. Let me know, if there is something that I'm overlooking
currently! Finally, what about the method 'custom_errors'; would that help?
