                                  Changelog

Daniel S (3 Dec 2007)

- Michal Marek introduced CURLOPT_PROXY_TRANSFER_MODE which is used to control

  the appending of the "type=" thing on FTP URLs when they are passed to a

  HTTP proxy. Some proxies just don't like that appending (which is done

  unconditionally in 7.17.1), and some proxies treat binary/ascii transfers

  better with the appending done!

- A bug report on the curl-library list showed a HTTP Digest session going on

  with a 700+ letter nonce. Previously libcurl only support 127 letter ones

This release includes the following changes:

 o --data-urlencode was added

 o CURLOPT_PROXY_TRANSFER_MODE was added

This release includes the following bugfixes:

libcurl does not do a complete ASCII conversion when doing ASCII transfers

over FTP. This is a known limitation/flaw that nobody has rectified. libcurl

simply sets the mode to ascii and performs a standard transfer.

.IP CURLOPT_PROXY_TRANSFER_MODE

Pass a long. If the value is set to 1 (one), it tells libcurl to set the

transfer mode (binary or ASCII) for FTP transfers done via an HTTP proxy, by

appending ;type=a or ;type=i to the URL. Without this setting, or it being

set to 0 (zero, the default), \fICURLOPT_TRANSFERTEXT\fP has no effect when

doing FTP via a proxy. Beware that not all proxies support this feature.

(Added in 7.17.2)

.IP CURLOPT_CRLF

Convert Unix newlines to CRLF newlines on transfers.
