I really don't know what you mean here. I'm still some what new to C  
programming and this is really my first time using something that  
isn't a POSIX library.

Yes that is what I mean by a bad or good url. If you go to a browser  
page with the url curl.haxx.se you get a 200 back as your code and if  
you go to curl.hexx.se you get a 404 back that is what I'm trying to do.

can i statically compile the lib?

Hello all
im new to this lib after searching the web for way to enable my
application to have http post/get sending
now i have 2 questions first is :
can i compile the lib to static lib so i can link it statically with
my application ?
second question is Because i need only basic operations of the http
protocol ( that is send http and recive http )
can i reduce some how the lib size ?
thanks

libcurl's a good way to do that!

Yes.  Make sure to configure libcurl with the --enable-static option
(which is the default), then link your application with the output of
`curl-config --static-libs` (this assumes a UNIX environment of some sort).

Yes, you can disable all the protocols and some features you don't want.
See the "reducing size" section of the docs/INSTALL file.

Not personally, but there's a big section on it in the INSTALL file, in
Makefile.vc6, in the FAQ, and in the mailing list archives.

Re: can i statically compile the lib?

ok i did it the documents i must say very clear
i compile with the HTTP_ONLY flag in wni32
and the static lib is 480 KB (491,540 bytes)
that is big for me is there any way to make it smaller ?

An optimized HTTP-only libcurl static library for x86 under Linux is about
175 KB.  It could be that your library includes debugging symbols,
or you haven't eliminated all possible extras (e.g. the built-in manual).
If you compile and link a simple curl "hello world" program (look in the
examples directory) you'll get a much better idea of how much of that
is code and how much is overhead.

Ah, I see. Thanks for fixing it up.

Sorry, I'm afraid I won't be of much help. While I have some experience
with autoconf, I have no clue about NetWare (despite being employed by
Novell ).

This can be done using the easy interface and multiple threads, or using the 
multi interface in a single thread (with some caveats).

Cannot control them in what way?

If you're sharing a share "object" from multiple simultaneous threads you need 
it. If you're carefully only using one at a time you won't need it.
