Then you'll have to track that first thing a user does a bit more carefully. Instead of storing it in something like Session.conferenceID, create an array within the session to correspond to individual browser windows, and when a user chooses a conference you can see whether the user was already working on that conference - and if not, stick it in a new array position: Session.conferences[1].id = ... Session.conferences[2].id = ... As a user works on a conference, you could pass a unique identifier other than the conference ID along through the form-driven editing process, to ensure that edits are coming from the same browser (which is basically the suggestion I made in my previous response). But honestly, you probably won't even need to do that - you know the path of the editing process, so you know when a user goes to the first step of the process they're starting a new edit.

Re: multi sessions in one
In this case, you can't store that information in the session. You'd have to do something like passing all the request specific keys in the URL from page to page. ?confID=xxx. Then, when you build your URLs, pass them along on every link. There isn't a way to send different cookies back from different windows of the same brower...

Imagine you have a big system designed to manage big events like annual conferences wirh inscription, payments, etc.. The first thing the user will do is select the conference he wants to work with, then the id of this conference is stored in a session variable. All he will do any further wil be done on this conference. It is impossible to do anything without first selecting the event. But suppose he opens a new window in which he selects another conference, the session variable will contain the id of this new event. Then anything he does using the first window will be done on this new conference, and this may cause trouble. ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:353029 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

This is pretty common - I see people doing it all the time. You can prevent session-based race conditions by using CFLOCK around any code that reads or writes session variables, where (a) a race condition might occur, and (b) you actually care about the outcome of that race condition - for example, if the user causes two database queries to fetch data rather than one, but the data is the same in both queries, you don't care about the outcome. You can create an identifier in the session scope that corresponds to a specific browser instance - setting the value initially on the first page load, for example - and making sure that token is passed back on each page request and that it matches the stored value. But if you simply use CFLOCK, you probably don't need to bother with this.

multi sessions in one
Hi, I've noticed that one of my users was causing errors in my application because he opens several windows to work in different areas of the system in the same time. This causes conflicts in the session scope, since all of his windows are having the same cookie, therefore the same session. This person is now aware of the problem and is not using several windows anymore, but just out of cutiosity, does any one see how I could detect such behavior? ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:353026 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

How do I code French accents in a CFMail (HTML format) ?
I have a bilingual website and on the French side I need to send out a standard email that includes some accented characters. I have tried several techniques, including using the HTML notation (e.g., é) and just letting the characters be imbedded in the body, but it doesn't look right when received. I have tried it with charset="ISO-8859-1" and with utf-8. No difference.
