check_http - make use of libcurl

[riskersen]

On IRC we discussed the possibility of extending check_http for more authentications mechanisms.

In the end, we agreed with libcurl, which would add some benefits to check_http

• authentication protocols like NTLM, Kerberos, instead of only Basic to server and proxy
• improved proxy support
• selectable network interface for outgoing traffic
• proven HTTP interface/features
• follow redirects
• HTTPS feature like specific SSL version and encryption

and so on, please see https://curl.haxx.se/docs/features.html for details.

From my perspective, this would lead to a complete rewrite, but the benefits aren't deniable.
Of course, we could also use libcurl for the check_ftp, but this would be another topic.

Unfortunately, i don't think i'm able to work on this request, due to the lack of deeper C knowledge.

What do you think about that?

We are in contact with the author of https://github.com/andreasbaumann/nagios-plugin-curl and will try to merge that one because its exactly what we are looking for already.

These are very good news.

For the record, and since it came up on -devel recently: the nagios-plugin-curl repository URL has moved but apparently has been incorporated as a feature branch already. \o/

Adding additional authentication methods in check_curl is on the todo list:

well, check_curl is there, therefore I am closing this
