Downloading twice

[Antonio Gomes]

hi all ,

I am facing a problem in my embedding app: it is not possible to
download the same file twice through a link click. It works like this:
at first time , it works fine , but if I cancel the download (UI
stuff) in the middle and then click in the link again to activate the
link and the download it does not load.

that is the LOG I have

I suspect problem is in nsHttpChannel::OpenCacheEntry , once if I
comment out some lines of code in this method downloads work fine in
the second time. Maybe cache problem, not sure ... Btw, I am using
memory cache (not disk cache).

Any tip ???

thanks
