459 If the form you're trying to submit uses the type 'multipart/form-data',

554 You can always replace the internally generated headers with -H/--header.

729 3.22 curl -X gives me HTTP problems
731 In normal circumstances, -X should hardly ever be used.
735 "curl http://example.com" it will use GET. If you use -d or -F curl will use
736 POST, -I will cause a HEAD and -T will make it a PUT.
739 does for you, you can override those request methods by specifying -X
740 [WHATEVER]. This way you can for example send a DELETE by doing "curl -X
743 It is thus pointless to do "curl -XGET [URL]" as GET would be used
744 anyway. In the same vein it is pointless to do "curl -X POST -d data
746 request-body in a GET request with something like "curl -X GET -d data
749 Note that -X doesn't actually change curl's behavior as it only modifies the

768 An example that would invoke a remote CGI that uses &-symbols could be:

790 them for the curl URL "globbing" system), use the -g/--globoff option:
792 curl -g 'www.site.com/weirdname[].html'

1095 5.1 Is libcurl thread-safe?
1099 We have written the libcurl code specifically adjusted for multi-threaded

1134 mem->memory = (char *)realloc(mem->memory, mem->size + realsize + 1);
1135 if (mem->memory) {
1136 memcpy(&(mem->memory[mem->size]), ptr, realsize);

1324 return data in a machine-readable format that can be parsed for type. The
1329 and NLST tend to hide unix-style hidden files (those that start with a dot)
