Hello,
i've a website application developed by ASP.Net 4, i deployed it in IIS (Windows7, IIS7) i created a special pool for this application... it works fine.

The problem now, when the user falls in recycling time the application says that there's an error (object reference) which means that the process w3wp.exe changed! so when the user wants to affect an adding of new data it doesn't work (error) so he should try to log in an other time to work that... is there any solution for that?? please i'm really sucking here :)

Thank you

If you search the exact error message by Google you will find the cause and solution.

I don't fully understand your problem but it sounds like you are saying your session is timing out. When the application pool is automatically recycled it hands off the information to the other process starting up and this is such a quick process that I doubt your user is hitting it as you say "in recycling time." It likely is a session timeout but I guess we need more information. Either way, you can increase the session timeout or turn off app pool recycling.

the problem is that i can't turn of the recycling... and yes what u understood is true, it's bcz when the process starts a new when (when the recycle execute) so all sessions closed that's what i discovered, so is there any other way to save date in a variable or object like session but it doesn't have a time out or something like that?? when i deactivate the auto recycle the process still increase and that gonna cause a block for the application... so :s

You can move your session into the State Server or into SQL. The Windows SDK or .Net SDK has an ASP.Net Session State Service and you can change your web.config to use the state service instead of IIS's RAM, that when when the App pool recycles your session is not lost. http://msdn.microsoft.com/en-us/library/ms972429.aspx

the resume of what i got about asp.net session state is:

1- if the config.web file exists with the application it's enough to modify in it
2- this is the code that we have to add or modify:
<configuration>
<sessionstate
="" mode="inproc" cookieless="false" timeout="20" sqlconnectionstring="data source=127.0.0.1;user id=<user id>;password=<password>" server="127.0.0.1" port="42424">

the 127.0.0.1 is the server's ip adresse right? but i still didn't get the inproc and the outproc yet :s when can i use in or out... ??? about Port it's the local host port that we're working on right? like localhost:83 the port here is 83 right??

sorry the code is cached in the comment
mode="inproc"
cookieless="false"
timeout="20"
sqlconnectionstring="data source=127.0.0.1;user id=<user id="">;password=<password>"
server="127.0.0.1"
port="42424"

i guess in my case i should work with out-of-process right ryanb31 ???

Kenz Kenza 30-Jan-12 17:01pm

sorry for all those cmnts :) i've an other qst and i think it's the last,it's about the session in the server side not RAM: every user got his own session even if the sessions got the same name????????????????????????????????

ZurdoDev 31-Jan-12 7:51am

Yes, a session object is specific to each user. Referring to the url I provided if you look at the section titled "Out-of-process Mode" it mentions that the .Net SDK has a program named ASPState and provides a sample web.config entry where you set mode="stateserver". Yes, the IP is for the server where you install the ASPState on, likely the same server where IIS is. This will start a new process that you can see in task manager and your session information will actually be stored in there so that when you recylce the app pool, your session state is not lost.
