Hi there,
I was wondering if HAProxy helps in the following situation:
- We have a wiki site which is quite slow
- Regular users don't have many problems
- We also get crawled by a search bot, which creates many concurrent
connections, more than the hardware can handle
- Therefore, service is degraded and users usually have their browsers
time out on them
Given that we can't make the wiki faster, I was thinking that we could
solve this by having a per-source-IP queue, which made sure that a
given source IP cannot have more than e.g. 3 requests active at the
same time. Requests beyond that would get queued.
Is this possible?
Maybe with http://haproxy.1wt.eu/download/1.3/doc/configuration.txt
src <ip_address>
fe_sess_rate
In the acl section.
Maybe you get some ideas from this
