==============================================================================
We pronounce curl with an initial k sound. It rhymes with words like girl
and earl. This is a short WAV file to help you:

+ https://media.merriam-webster.com/soundc11/c/curl0001.wav
There are numerous sub-projects and related projects that also use the word
curl in the project names in various combinations, but you should take
very well at the side. Curl's output can be piped into another program or
redirected to another file for the next program to interpret.

+ The ca cert bundle that used to be shipped with curl was very outdated and
must be replaced with an up-to-date version by anyone who wants to verify
peers. It is no longer provided by curl. The last curl release that ever

Yes, SOCKS 4 and 5 are supported.
- 2.5 Install libcurl for both 32bit and 64bit?
-
- In curl's configure procedure one of the regular include files gets created
- with platform specific information. The file 'curl/curlbuild.h' in the
- installed libcurl file tree is therefore somewhat tied to that particular
- platform.
-
- To allow applications to get built for either 32bit or 64bit you need to
- install libcurl headers for both setups and unfortunately curl doesn't do
- this automatically.
-
- A commonly used procedure is this:
-
- $ ./configure [32bit platform]
- $ mv curl/curlbuild.h curl/curlbuild-32bit.h
- $ ./configure [64bit platform]
- $ mv curl/curlbuild.h curl/curlbuild-64bit.h
-
- Then you make a toplevel curl/curlbuild.h replacement that only does this:
-
- #ifdef IS_32BIT
- #include "curlbuild-32bit.h"
- else
- #include "curlbuild-64bit.h"
- #endif
-
3. Usage problems
3.3 Why doesn't my posting using -F work?
- You can't arbitrarily use -F or -d, the choice between -F or -d depends on the
- HTTP operation you need curl to do and what the web server that will receive
- your post expects.

doesn't require this, you don't need a client certificate.
A client certificate is always used together with a private key, and the
compilers or prior curl versions it may set a time that appears one hour off.
This happens due to a flaw in how Windows stores and uses file modification
times and it is not easily worked around. For more details read this:

4.14 Redirects work in browser but not with curl!
The reason for this is that we first generate the request to send using the
old 1.1 style and show that request in the verbose output, and then we
convert it over to the binary header-compressed HTTP/2 style. The actual
- "1.1" part from that request is then not actually used in the transfer.

5. libcurl Issues
libcurl will reuse connections for all transfers that are made using the
same libcurl handle.
- When you use the easy interface the connection cache is kept within the easy
- handle. If you instead use the multi interface, the connection cache will be
- kept within the multi handle and will be shared among all the easy handles

use that to figure out exactly when the right condition is met when the
transfer should get stopped.
