483 If the form you are trying to submit uses the type 'multipart/form-data',
484 then and only then you must use the -F type. In all the most common cases,

578 You can always replace the internally generated headers with -H/--header.
579 To make a simple HTTP POST with text/xml as content-type, do something like:
581 curl -d "datatopost" -H "Content-Type: text/xml" [URL]

723 curl --header "Host: www.example.com" http://127.0.0.1/
725 You can also opt to add faked host name entries to curl with the --resolve

744 curl -O -u user:password scp://example.com/~/file.txt
760 3.22 curl -X gives me HTTP problems
762 In normal circumstances, -X should hardly ever be used.
766 "curl http://example.com" it will use GET. If you use -d or -F curl will use
767 POST, -I will cause a HEAD and -T will make it a PUT.
770 does for you, you can override those request methods by specifying -X
771 [WHATEVER]. This way you can for example send a DELETE by doing "curl -X
774 It is thus pointless to do "curl -XGET [URL]" as GET would be used
775 anyway. In the same vein it is pointless to do "curl -X POST -d data
777 request-body in a GET request with something like "curl -X GET -d data
780 Note that -X does not actually change curl's behavior as it only modifies the
784 Accordingly, by using -XPOST on a command line that for example would follow
799 An example that would invoke a remote CGI that uses &-symbols could be:
801 curl 'http://www.example.com/cgi-bin/query?text=yes&q=curl'
808 using -d/--data you must encode it as '%25' (which then also needs the
821 them for the curl URL "globbing" system), use the -g/--globoff option:
823 curl -g 'www.example.com/weirdname[].html'
832 By using the --fail option you can tell curl explicitly to not get any data
856 The server has not found anything matching the Request-URI. No indication
861 The method specified in the Request-Line is not allowed for the resource
862 identified by the Request-URI. The response MUST include an Allow header

1122 5.1 Is libcurl thread-safe?
1126 We have written the libcurl code specifically adjusted for multi-threaded
1127 programs. libcurl will use thread-safe functions instead of non-safe ones if
1161 mem->memory = (char *)realloc(mem->memory, mem->size + realsize + 1);
1162 if (mem->memory) {
1163 memcpy(&(mem->memory[mem->size]), ptr, realsize);

1356 Also, both LIST and NLST tend to hide unix-style hidden files (those that

1385 The most flexible way is by writing your own time-out logic and using
