Some extra technical information: courses must be done on laptops with their configuration closely controlled, using Internet Explorer 8 (I think), with Windows XP.
Now, where it doesn't work: this new course has 5 tests. The two first tests have their answers stored in files with names like [email protected]~~local~~(path to the html file setting the cookie)_[X] with [X] being usually , but sometimes  and when it is , its name and content has been changed by another html file from another path.
From what I could see on the net, a file created under with one path cannot be modified by a second file from another path. Still it happens.
For a better idea, here is how things happen in order:
First test: creates first cookie file.
Second test: creates second cookie file.
Third test: truncates first cookie file, rename first cookie file (now ending with a ), and creates third cookie file.
Fourth test: deletes first cookie file, trucates and rename second cookie file, and creates fourth cookie file.
Fifth test: deletes second cookie file, truncates and rename third cookie file, creates fifth cookie file.
All those have different paths; yet saving new tests results cause previous cookie files to be modified/deleted.
For what I could see, the limit of the HTML header should be 4ko; each cookie file is way below that. And my understanding is that cookies from another path will not be passed in the HTML header.
So, I am at a loss. Is there some Internet Explorer extra limitation on cookies from the same domain? Is it the fact that it is created locally rather than from a server? Anyone has an idea of what is going on, and how to make sure older data doesn't get deleted?
(We have checked expiration dates. We have tried setting a path, but the format might have been wrong since no cookie file would be created at all.)
code:(I have tried adding +"path=http://localhost/path/to/file" between the expires value and the end of the statement, but it caused the cookie file not to be created at all.)
var excate=new Date;
Then this function is called each time a name-value pair needs to be kept (questions=answer plus some extra information about the test and course identification).
Would anyone have an idea of what is going on? Even a hint? Please?
Ok. I may have found the reason. Microsoft page on IE cookie limitations:
quote:Since the current usage surpass the 20 cookies limit, perhaps even the 50 one, we may have to concatenate cookies. Which is no good news on my part...
By default, Internet Explorer can store a maximum of 20 cookies for each domain. If a server in the domain sends more than 20 cookies to a client computer, the browser on the client computer automatically discards some old cookies.
