Description

At least DConf it was announced that the plan is to remove etc.c.curl (in fact entire etc).

With the "high-level" API there are many issues as well:

- no response object (it's impossible to access the response for e.g. the error code or other attributes, only via low-level)
- no simple support for custom header attributes
- no support to build query parameters
- no simple support for custom request parameter
- just throws CurlException (no fine-grained control of exceptions)
- post: no support for user-specified file type, no support for File or stream)
- no simple support for basic auth (only via low-level)
- no high-level support for streams (only ranges)

(I am pretty sure this list is longer)

and btw support of SSL is mandatory in 2016.
In general dlang-requests looks to be a very promising replacement (it does support linking with SSL or botan too):

It's modeled after the successful Python module requests:
