Why do I get problems when I use & in the URL? + + In general unix shells, the & letter is treated special and when used it + runs the specified command in the background. To safely send the & as a + part of a URL, you should qoute the entire URL by using single (') or + double (") quotes round it. + +10. Why do I get problems when I use {, }, [ or ] to use multiple URLs? + + Because those letters have a special meaning to the shell, and to be used + in a URL specified to curl you must quote them. + +11. Where can I find a copy of LIBEAY32.DLL so I can use the SSL version? + + Curl uses OpenSSL to do the SSL stuff. The LIBEAY32.DLL is what curl needs + on a windows machine to do https://. Check out the curl web page to find + accurate and up-to-date pointers to recent OpenSSL DDLs and other binary + packages. + +12. Why do I get downloaded data even though the web page doesn't exist? + + Curl asks remote servers for the page you specify. If the page doesn't + exist at the server, the HTTP protocol defines how the server should + respond and that means that headers and a "page" will be returned. That's + simply how HTTP works. + +13. Why do I get "HTTP/1.1 403 Forbidden" from a http server? + + RFC2616 clearly explains this return code: + + 10.4.4 403 Forbidden + + The server understood the request, but is refusing to fulfill it. + Authorization will not help and the request SHOULD NOT be repeated. + If the request method was not HEAD and the server wishes to make + public why the request has not been fulfilled, it SHOULD describe the + reason for the refusal in the entity. If the server does not wish to + make this information available to the client, the status code 404 + (Not Found) can be used instead. + +14. How can I disable the Pragma: nocache header? + + You can change all internally generated headers by adding a replacement + with the -H/--header option. By adding a header with empty contents you + safelt disables the headers. Use -H "Pragma:" to disable that specific + header. + +15. Can you please tell me what an error code 142 means? + + All error codes that are larger than the highest documented error code + means that curl has existed due to a timeout. There is currentl no nice way + for curl to abort from such a condition and that's why it gets this + undocumented error. This is planned to change in a future release. + +16. How do I keep usernames and passwords secret in Curl command lines? + + I see this problem in two parts: + + The first part is to avoid having clear-text passwords in the command line + so that they appear in 'ps' outputs and similar. That is easily avoided by + using the "-K -" contruct that causes curl to read parameters from stdin to + which you can pass the secret info. + + To keep the passwords in your account secret from the rest of the world is + not a task that curl addresses. You could of course encrypt them somehow to + at least hide them from being read by human eyes, but that is not what + anyone would call security. + +17. Does curl support javascript/ASP/VBscript/XML/XHTML or HTML version Y? + + To curl, all contents are alike. It doesn't matter how the page was + generated. It may be ASP, PHP, perl, shell-script, SSI or plain + HTML-files. There's no difference to curl and it doesn't even know what + kind of language that generated the page. + + Javascript is slightly different since that is code embedded in the HTML + that is sent for the client to interpret and curl has no javascript + interpreter. + +18. Does cURL support Socks (RFC 1928) ? + + No. Nobody has wanted it that badly yet. I would appriciate patches that + brings this functionality. + +19. Can I use curl to delete/rename a file through FTP? + + Yes. You specify custom ftp commands with -Q/--quote. |
