Re: [cpp-netlib-devel] Multiple requests from single agent

[Thomas K. <Jim...@gm...>]

Here you go, trimmed down to the essentials:
header (just for reference): http://snipt.org/xnlol
implementation: http://snipt.org/xnlok
Basically all I do is call the ResourceDataFromURL method - it then either:
a) directly starts a new request on the client or
b) queues a request

Once a callback has received all data it will directly start a new
request on the client (if there are any) and call the user-supplied
callback fn.

However on MacOSX I get some 2000 active threads before the
application dies on me. On Ubuntu I get a sigsegv instead on line 72 -
this is after calling ResourceDataFromURL 8 times in total.
Maybe the problem is that I use boost::shared_ptr to store the
requests - and once the callback quits, the shared_ptr will free the
request, thus any further actions the http client may do on the
request (free resources?) will cause unexpected behavior.
What do you think?

Kind regards,
Thomas
