Multithreading in Application_Error event handler?

[ram]

Hi,

In Application_Error (global.asax) i'm sending the details of the
exception to
a file (opening and closing file each time).

I'm using the same file (eg, log.txt) for all logs.

Are the calls to this method serialized?

It's possible that, when trying to write to the file, the file is
already opened by another thread?


TIA,
ram

In my experience, no.

Yes. If you want to write to the file from multiple threads, you need to
synchronize your code.
