Different context or session for each browser tab

Hi,

Is it possible to have different context or session for each browser tab as it was in vwg with vwginstance keyword?

Best regards,

Yes, there are two (maybe more) ways:

• Wisej creates a new session when the arguments in the URL are different. So you can create a new session simply by adding ?any_name=a_new_value. i.e. http://localhost/myapp?session=13124, http://localhost/myapp?session=877348... the number or string can be random, a timestamp, a gui, your own value. Wisej will preserve the session on a refresh when the URL matches.

• Other way (similar to VWG): you can enable cookieless sessions in the app JSON: "cookieless": true. When the session starts Wisej will add it to the URL. http://localhos/myapp becomes http://localhos/myapp?sid=fd12b081-5d4a-4cae-a513-47543f694f4c. This is preserved on a refresh. But you type or link the url to a new tab, Wisej automatically creates a new session and adds it to the URL.

HTH

Best,

Hi Luca,

I've tested the ways you explained,

"cookieless sessions" option runs very well as you explained.

On the other hand, may the first option run a bit different? If I use url argument name "sid" with any value (sid=1, sid=anyvalue) it's ok, every tab starts a new context/session  from the beginning as the first option. But if I use random argument name and value (abc=1, xyz=anyvalue),  new tabs starts with previous tab's state.

Serkan,

Yes, my bad. It was like that but it was changed. Now the new set of arguments is updated instead of reloading a new session. This lets your code process different arguments in the URL without recreating the session. Changing the URL causes a reload anyway. You can get notified of a refresh or change of arguments by attaching to:

Application.ApplicationRefresh += ...

The arguments in the URL are available using this collection:

Application.QueryString

If you use "sid" and "cookieless" is false when you hit refresh Wisej will always start a new session since sid is invalid. In fact that is a "trick" to use when debugging to force the start of a new session. I add "?sid=new".

Any chance of adding an option for when the Default.json file contains:

"cookieless" : true

To say something like:

"embeddSID" : true

So that the sid=GUID is contain in the page instead of the URL ???

It would make for a lot cleaner URL's and make it easier when additional parameters are used on the URL.

The only reason to have it the URL is to preserve the session on a Refresh or F5. Otherwise each refresh (or a retry after a network loss) would create a brand new session.
