Arun,

In our use of the cookie file, we've come across no locking mechanism (have you found one?). We simply adjust our script/program to accommodate the 'life' of the cookies, and either read, or re-create the cookies accordingly. The cookie 'lifespan' - the expiration - is usually a function of the object website you're attaching to, no?

Regards, Lou Picciano

Subject: cookie file used by CURL

Hi,

I have two instances of my application running at the same time. It uses CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR options.
Since it is the same application that is running, CURLOPT_COOKIEFILE is set to the same file. The application would be talking to different http servers based on how it is invoked and the command line arguments passed.

Will curl ensure that the cookie file is locked and unlocked before and after writing to it respectively in order to avoid data inconsistancies and race conditions.

Thanks,
Arun
