Re: Application Design for User Authentication
On 28 Aug 2002 at 11:57, Gfoo opined: G:I'm creating a web appication in Perl (and CGI). G:I' ve written code that is used to create and read sessions (by using G:cookies or GET http method) which are used after authenticating user logins G:in a database. G:The code for handing transitions and state is about 60 lines of code. I G:already have made it modular, but I'm still searching for an elegant way to G:use this code on every script. G:I have several pages (.pl scripts) that must be viewable only by logged in G:users. G:Do I need to put the same code on every page (and have the 'actual' script G:code in an if branch of the authentication code)? G:I also have thought that I can create something like a dispatcher, which G:checks if the user is authenticated and then call the actual .pl script (or G:modules subroutines) from there. G:How can someone avoid code repetition on all scripts that require G:authentication? Can I avoid having a big if ... statement to handle all G:cases? It would be nice, if only 1 to 5 lines of code were required on each G:script. Is there any suggested way of handling this situation? can you use mod_perl? intercepting the authentication step with mod_perl is very easy and will accomplish exactly what you want to do. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: sendmail command line (without queuing)
Ok Ok, I am glad that Net::SMTP is better. I prefer it because I could use the same code in Windows and Unix and I heard that using sendmail could create some security problems, but I thought that sendmail could be more reliable, or could work faster, etc. Teddy's Center: http://teddy.fcc.ro/ Mail: [EMAIL PROTECTED] - Original Message - From: Wiggins d'Anconia [EMAIL PROTECTED] To: Octavian Rasnita [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Wednesday, August 28, 2002 5:51 AM Subject: Re: sendmail command line (without queuing) Would be interesting to know which book and what reasons they stated for using sendmail directly. I would imagine most of the people on the list and myself included would advocate using the module in almost all cases. There are a couple of big reasons, mainly that understanding sendmail is a huge huge task, sendmail is probably one of the most complex software packages on the internet, using a module to direct all of its intricacies written by someone else whom probably has a better if not very good understanding of the underlying core technology, in this case sendmail, is better than trying to learn just a couple of things about sendmail to accomplish what you want, while this works in throw away scripts that only get used once or twice, for any sort of real programming (as drieux puts it) project you are going to want the robustness the module can provide in a relatively simple interface, again which the module provides. Second by using the module you remove yourself from having to keep abreast of the latest changes to SMTP and the sendmail specs, etc. which if you are into and it is a core part of your development that may be fine, but for most of us we have enough to keep track of with respect to browsers, web servers, databases, perl itself, the OS, etc. being able to just upgrade the module and leave the changes required for it to interface with sendmail to the module developer relieves one burden. Finally, when in the future your code has to get maintained by someone else, using a module as standard and well documented as most in CPAN are and in the case of Net::SMTP specifically will be much easier on that other person as there is a good chacne they are already familar with it or they can quickly get spun up on good docs. Certainly there are times when calling sendmail directly may be appropriate but in most cases, 99 out of a 100, using the module is probably going to be better in the long run. As for using Net::SMTP or any of the other mail modules is probably system dependent, and is certainly influenced by user opinion, we all have our preferences. A quick search on CPAN returns 149 :-)... http://search.cpan.org/search?mode=allquery=sendmail Remember to throw comments back to the list as well, I would love to hear what others think, does anyone disagree, should we cast aside the module and go with the direct route (other than the fact that this sends us down the evil path to the dark side, drieux?)... -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
.htm?
Hi all, I've seen some links that end in .htm?blabla=blublu Can you tell me what kind of html files are these? Are they Perl CGI programs that have the .htm extension?

For all you know, that request triggers a database lookup to generate a response. The only way to know for sure is to have access to the server's configuration so you can see exactly how a particular request would be handled. Now we can speculate, and guess that links like those probably point to some kind of ASP-like pages. Perhaps PHP, HTML::Mason, Embperl, etc. Or, they could be conventional CGI scripts with a .htm extension. Again, you simply cannot tell from the request itself. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
