Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

Multiple users with same session id

  • Multiple users with same session id

    Can this happen? How can it be fixed?

    Multiple users login to the app and have session var set to filter for their own records. On the server I watch the session folders with their session id get created and the app writes a text debug file with their user id. OK so far.

    However it has happened that another user logs on and has the same session id, so has the same session folder. The app writes the debug file, and of course the user id is different. now when the first user requests a page they get data for user 2.

    This must mean that different users have a cookie with the same session id. This is of course a disaster. What to do?

    I am about to start converting this old app to a5v12, but this needs to be corrected immediately.

    Older versions of the server allowed session ID recycling, which could lead to this. I do not remember exactly when it was changed, but versions 11 and 12 definitely do NOT have this problem and I highly suspect 10 does not either.

      Re: Multiple users with same session id

      Thanks Lenny. For a "today" solution, would it work to have the user clear cookies from their browser and then they would get a new, hopefully unique, session id? Is there a more targeted way to clear just the WAS cookie? These are remote and non-technical users, but I'm sure they will cooperate if it solves this problem.

      If the session id is a uuid, curious that duplicates get assigned.

        Clearing cookies may not be enough. If they are using a link/bookmark that has the session ID as part of it, they will use that same session ID again.

        If it is a known session ID that keeps appearing, you could add code to your pages that looks for that session ID and do a Session.Abandon() (if that exists back in V9).

          Understood about the bookmark. Will check that case by case.

          Since this is short term, would it work if I set the WAS to not use cookies, forcing tracking through url? Then I don't need to rely on users to do anything.

          Not sure if there is unintended consequence to that.

            Re: Multiple users with same session id

            The issue is that the older server would trust any session id requested by the browser. This could be from a cookie, or from a link with a session id in it. In order to have occurred in the first place, a link with the session ID was shared between users at some point, so there is a fair likelihood that clearing cookies or even turning them off will not fully solve this. There were also a number of bugs in cookieless session tracking that have been fixed over the years. For thos 2 reasons, I would not turn off cookies in an attempt to fix this.
