last http headers

[Tom Glod]

Hi folks,

Does anyone know when the content of the last sent and received http header
functions are updated?  i'm having a lot of trouble saving the headers when
scheduling and sending multiple http requests async style

sometimes the function gives the correct ones, sometimes not....I can't
nail it down, so i figured i should find out when the update happens
exactly.

so far i am working on simple get requests if that matters.

Thanks for any help on this.
