Re: use of fid_ with http

[Tarik Alj <aljtarik@ozias.inrs-telecom.uquebec.ca>]

Thanks for your fast answer.

I thought id_ (from Node) was used for this purp. That's what the code appears 
to do:

http-agent.tcl: Http intsproc init { ns node } {... $self set id_ [$node_ id] 
...} .

>From the code in http-agent.tcl, http-server.tcl, http-client.tcl, 
http-cache.tcl, I found out that fid_ was only used with Htpp:getfid in 
Http::connect and http/Server::alloc-connection.

So I've overrided Http::getfid so as to always set fid_ = 0. It seems to work 
fine for what I need (bursty, exponential traffic). 

Now I would like to know if what I've done can have a *desastrous* impact on the 
traffic, if I can reasonnably use it; or if I should switch to 
large-scale-web-traffic.tcl.
