Hi. I'm trying to figure out how Webdev manages sessions. I've been reading the PCSoft documentation about AWP Contexts, but I don't get to fully understand it; I really miss a good tutorial or full example on how to manage AWP contexts.
In PHP it is very easy to understand and manage session variables:
How can this be accomplished with Webdev? Is it even possible?
Is there any good documentation, article, video, etc... explaining how to properly manage sessions?
All I need is a simple example showing how to store and retrieve sessions variables.
Thank you very much. |

Hi
In AWP mode, I personnaly manage my variables myself, in the DB. I just
pass a session ID as parameter to all pages, and when I have
getVariable and SetVariable functions that read and write in a parameter
file when needed.
Very simple, very robust, no limits, and does not rely on anything
outside my code.
Best regards

How do you manage dead sessions ?
Have you implemented some mechanism to detect dead sessions (inactive,
timed-out ...) or you arbitrary throw away session after some
predefined period of inactivity ?

Hi,
How do you manage dead sessions ?
Have you implemented some mechanism to detect dead sessions (inactive,
timed-out ...) or you arbitrary throw away session after some predefined
period of inactivity ?
It depends on the need of the website...
Mostly, I store the last time the session is called (ie in the page init
area of the main page template) inside the session record.
In some cases, I have a keep alive mechanism in the page template
calling the server every n minutes to keep the session alive
And of course, during each call to the session, I verify that the
session is valid based on the requirement of the web site:
- it can be a simple time out (more than the n minutes, ie the browser
is closed)
- it can also be a check on the IP calling in
- It can also be a check on a browser/pc fingerprinting (type of
browser, version, language, etc)
- and of course, I also know that way if the session is anonymous or if
the user is logged in, which user, his rights, etc
- This ALSO allows me, if needed, to get BACK to a session content (cart
content, by example) several days later when the user/pc is identified
It's fully flexible as I can code basically anything inside that
standard mechanism
Best regards

I think that Mr. Harari's solution is a very clever one: It really has convinced me, and I'll try to convince my boss to apply it. Thank you.
However, may I ask you something, please? Why don't you rely on native Webdev mechanism (AWP contexts)? I mean, reading your answers, it seems to me that it's still not as a good method for managing sessions as you would wish.
Don't you think that it's kind of a pity that Webdev is still not able to replicate the behaviour of PHP, in such an easy and simple way? I also find it a big limitation the fact that I can only store simple-type variables in contexts...
By the way, I still would like someone to explain to me how exactly AWP contexts work.
Thank you very much.
PS: Please keep in mind that I'm totally new to web development in general, and specially to Webdev. Maybe I'm asking stupid questions. In that case, please excuse me... and teach me a little bit on the matter  |

Hi again,

Webdev is able to do much more than php (in classic/intranet/extranet
mode) if you don't need SEO.
As for the awp mode, the session management system I described is just a
few hours of development, so I certainly do not count that as a big deal.
And as for all standard mechanism (being PHP or anything else), they are
only good as long as you have standard needs, and my personal experience
is that my customers are rarely cookie cutter shaped. So I prefer to
build a mechanism like this one from scratch so that I have FULL
flexibility.
By the way, I still would like someone to explain to me how exactly AWP
contexts work.
I'm not sure what else to tell you that isn't already there:
https://doc.pcsoft.fr/en-US/?3539060&name=awp_gestion_des_contextes
Basically, you declare a context mode (client cookie or server disk) and
webdev saves your variables at the chosen place when you asks it to then
retrieves them later.
So my system is basically working the same way, except that I do not
have any of the limitations described in the help, and I can add easily
other functions to the system.
Best regards

The problem I have with that documentation is that I find it a bit confusing. Of course, that's probably because of my newbie condition, but I still miss a good and brief piece of code that demonstrates how AWP contexts work, in the way of the screenshots I posted before.
On the other hand, I'm very grateful for your attention. My boss also liked your idea and I'm already working on it. I'm learning a lot. Thank you. |
