[cpp-netlib-devel] Having some questions on cpp-netlib

[Александр М. <am...@ma...>]

 Hello!

 Sorry, I am not a developer, I am simply interesting on cpp-netlib library, but I was not found any support mailing list.

 My questions are:
1) HTTP client and SSL. How I can compile client without HTTPS support (which adds dependency on openssl library). I try to define BOOST_NETWORK_NO_HTTPS, but it not work. I try to lookup in code for BOOST_NETWORK_NO_HTTPS or BOOST_NETWORK_HTTPS, but there is no occurences found.
Some https features found in boost\network\protocol\http\impl\sync_connection_base.hpp, but they are unconditional and can't be stripped.

2) cpp-netlib is hard C++ library, and I can't understand it.
I think that HTTP server (in sample) is serial (not a parallel) and handles requests consistently. Hard worker requests can easy get denial of service when incoming connection overfull connection accept queue. I am right? Is the way to make parallel server, which handles requess in different threads?

3) Is there way to stop client from other thread?
Such illustrated above:
-- worker thread --
client.get(); // client.post() etc
-------------------

-- GUI thread --
if (canceled && client.in_progress()) client.abort();
----------------

Or, may be there is the way to install callback which periodicaly receives client status events (such as "resolving", "connecting", "awaiting_reply") and can return value to signal that abort needed (true for continue, false to abort, as sample)

Or, may be client can be used in async mode such here:
client.get();
while( not canceled and client.in_progress() and not client.done()) {}

4) Is there the way to make secure (https) server?
 

Thank you for your attention,
                              Alex Martynov.

Hi Alex, I'm currently in the middle of a project that is requiring my 100%
attention, so I may not be able to respond right away. I'll let the others
on the list respond but I am working on an asynchronous client
implementation. I'll say more when I'm at a full computer. Hope this helps.

 Thanks Michael, I hope that async client will be coming soon.

What version of cpp-netlib are you using?  There was a discussion about this
a month and a half ago and the decision was to define a macro
BOOST_NETWORK_ENABLE_HTTPS in order to explicitly opt-in to using SSL.
 However, this has not yet been implemented.  It is not possible to compile
the HTTP client without SSL in the current release (0.6).

The internal details can be quite obscure, but it is a stated goal that
using the library should not be hard to do.  Admittedly, the documentation
is still incomplete but I am making an effort to make it more accessible.
 If you have anything specific you want addressed, please let me know and I
will try to deal with it.

I think you're right.  The HTTP server provided is very simple, but
eventually cpp-netlib ought to provide the building blocks for more complex
servers.  I know Dean has more ideas on this, he could let you know more
about his plans.

As Dean already mentioned, he is working on an asynchronous HTTP client so I
will leave it to him to respond more fully to this.

Yes, but as with (2) it's simply a matter of implementing it.

I am using version 0.5 of cpp-netlib. I was read that discussion, but wasn't understand
is that implemented or not. I think this point is important to implement - library will
be more lightweight when external dependecies will be removed.

Usage is quite simple, if that described in documentation ;)
But its much incomplete, and research for details is difficult.
