  1.2 What is libcurl?

  libcurl is a reliable, higly portable multiprotocol file transfer library.

  libcurl is a reliable and portable library which provides you with an easy

  interface to a range of common internet protocols.

  Any application is free to use libcurl, even commercial or closed-source

  ones.

  You can use libcurl for free in your application even if it is commercial

  or closed-source.

  1.3 What is cURL not?

  available way to do multiple requests was to init/perform/cleanup for each

  transfer.

  5.4 Does libcurl do Winsock initing on win32 systems?

  5.4 Does libcurl do Winsock initialization on win32 systems?

  No.

        For VC++ 6, there's an included Makefile.vc6 that should be possible

        to use out-of-the-box.

        Microsoft note: add /Zm200 to the compiler options, as the hugehelp.c

        won't compile otherwise due to "too long puts string" or something

        like that!

   This is a probably incomplete list of known hardware and

   operating systems that curl has been compiled for:

        curl ftp://ftp.funet.fi/README

  Get a gopher document from funet's gopher server:

        curl gopher://gopher.funet.fi

  Get a web page from a server using port 8000:

        curl http://www.weirdserver.com:8000/

        curl ftp://cool.haxx.se/

  Get a gopher document from funet's gopher server:

  Get the definition of curl from a dictionary:

  -D/--dump-header option when getting files from both FTP and HTTP, and it

  will then store the headers in the specified file.

  Store the HTTP headers in a separate file:

  Store the HTTP headers in a separate file (headers.txt in the example):

        curl --dump-header headers.txt curl.haxx.se

  -F accepts parameters like -F "name=contents". If you want the contents to

  be read from a file, use <@filename> as contents. When specifying a file,

  you can also specify which content type the file is, by appending

  ';type=<mime type>' to the file name. You can also post contents of several

  files in one field. So that the field name 'coolfiles' can be sent three

  files with different content types in a manner similar to:

  you can also specify the file content type by appending ';type=<mime type>'

  to the file name. You can also post the contents of several files in one field.

  For example, the field name 'coolfiles' is used to send three  files, with

  different content types using the following syntax:

        curl -F "coolfiles=@fil1.gif;type=image/gif,fil2.txt,fil3.html" \

        http://www.post.com/postit.cgi

  If content-type is not specified, curl will try to guess from the extension

  (it only knows a few), or use the previously specified type (from an earlier

  file if several files are specified in a list) or finally using the default

  type 'text/plain'.

  If the content-type is not specified, curl will try to guess from the file

  extension  (it only knows a few), or use the previously specified type

  (from an earlier file if several files are specified in a list) or else it

  will  using the default type 'text/plain'.

  Emulate a fill-in form with -F. Let's say you fill in three fields in a

  form. One field is a file name which to post, one field is your name and one

  field is a file description. We want to post the file we have written named

  "cooltext.txt". To let curl do the posting of this data instead of your

  favourite browser, you have to check out the HTML of the form page to get to

  know the names of the input fields. In our example, the input field names are

  favourite browser, you have to read the HTML source of the form page and find

  the names of the input fields. In our example, the input field names are

  'file', 'yourname' and 'filedescription'.

        curl -F "file=@cooltext.txt" -F "yourname=Daniel" \

             -F "filedescription=Cool text file with cool text inside" \

             http://www.post.com/postit.cgi

  So, to send two files in one post you can do it in two ways:

  To send two files in one post you can do it in two ways:

  1. Send multiple files in a single "field" with a single field name:

        curl -F "docpicture=@dog.gif" -F "catpicture=@cat.gif" 

REFERER

REFERRER

  A HTTP request has the option to include information about which address

  that referred to actual page, and curl allows the user to specify that

  referrer to get specified on the command line. It is especially useful to

  that referred to actual page.  Curl allows you to specify the

  referrer to be used on the command line. It is especially useful to

  fool or trick stupid servers or CGI scripts that rely on that information

  being available or contain certain data.

  Note that by specifying -b you enable the "cookie awareness" and with -L

  you can make curl follow a location: (which often is used in combination

  with cookies). So that if a site sends cookies and a location, you can

  use a non-existing file to trig the cookie awareness like:

  use a non-existing file to trigger the cookie awareness like:

        curl -L -b empty-file www.example.com

        curl -L -b empty.txt www.example.com

  The file to read cookies from must be formatted using plain HTTP headers OR

  as netscape's cookie file. Curl will determine what kind it is based on the

  file contents.

  file contents.  In the above command, curl will parse the header and store

  the cookies received from www.example.com.  curl will send to the server the

  stored cookies which match the request as it follows the location.  The

  file "empty.txt" may be a non-existant file.

PROGRESS METER

SPEED LIMIT

  Curl offers the user to set conditions regarding transfer speed that must

  be met to let the transfer keep going. By using the switch -y and -Y you

  can make curl abort transfers if the transfer speed doesn't exceed your

  given lowest limit for a specified time.
