I'm so glad to see that haproxy is finally adding native SSL support.

I have used stunnel (http://www.stunnel.org/) in front of HAProxy up to now. That setup works. But I'm happy that in the future I can remove one of the moving parts from my machine and just use haproxy.

Great to see another hole in secure connections being plugged.

I wonder if it supports SNI for virtual SSL hosts?

erichocean• 14 years ago

+1 If it did, that'd be really, really helpful.

The spec is pretty simple, I don't know why SSL implementations leave it off. :(

daniellockard• 14 years ago

Because Windows XP doesn't support SNI, so not many people use it. That's my theory.

It does http://permalink.gmane.org/gmane.comp.web.haproxy/8134 Last I heard, it was buggy unless you used a specific build from April http://blog.exceliance.fr/2012/04/13/enhanced-ssl-load-balan... but it may have improved since.

This is great, exactly when I need it.

What I would like to see is a way to change the HAProxy configuration on the fly, or something like a configuration backend. That would avoid reloading HAProxy after each config change, and allow a much more flexible configuration.

cdavid• 14 years ago

Why is haproxy reloading an issue ? It works pretty well in my experience (although I am not in the web business anymore, so things may have changed in the last two years).

bastichelaar2• 14 years ago

Reloading is no issue when you have few frontends or backends. But when you have a lot of front- or backends, the configuration file will be huge, and reloading will take some time. If you need to reload every few seconds, this might even cause downtime. But I guess our workload is not the usual implementation of HAProxy...

I can not build it in Fedora (both 12 and 16). Ubuntu is fine.

"include/proto/proto_http.h" defined "error_message", this is in conflict with the "error_message" already defined in "et/com_err.h", which is included by "krb5/krb5.h", which itself is included by "openssl/kssl.h", which included by "openssl/ssl.h"

Where do I submit a bug report? Couldn't find the link on haproxy site.

just use the software-engineering 2.0 way (vc but not github) and send a mail to their mailing list: haproxy@formilux.org

Can anyone tell me how HAProxy compares to Varnish? I've used the latter and swear by it, but I've never used HAProxy. Is it as amazingly fast at caching as Varnish is?

Right now I do nginx (for SSL) -> Varnish (caching) -> nginx (static media/proxying) -> gunicorn (Django). I'd love to remove many of those parts.

wmf• 14 years ago

Last I heard, HAProxy does not perform any caching. I agree that fewer components in the stack would be an improvement, but we seem to be in the minority.

ibotty3• 14 years ago

you are part of a vocal minority. there is a reason though for the unixy model of operation with more (well-defined as proxys usually are) smaller components.

ibotty3• 14 years ago

see the official haproxy blog about it: [1] and [2]. i think it's a valid comparison. but as i said in my submission of the first of these articles, there are some (minor) mistakes.
