AW: Fallback Server

["Burian Peter (OI&T V)" <peter.burian@xxxxxxxxx>]

Hi!

We use ldirectord. What i would like is to use specific "sorry URL" for each
virtual server (=application).

something like this:

# Application1
virtual=10.12.30.58:80
        real=10.225.30.52:8080 masq
        real=10.225.30.53:8080 masq
        service=http
        request="index.html"
        receive="A1"
        scheduler=wlc
        persistent=21600 # 6h
        protocol=tcp
        fallback=127.0.0.1:8080/app1/sorry_app1.html

#Application2
virtual=10.12.30.63:80
        real=10.225.30.57:8080 masq
        real=10.225.30.58:8080 masq
        service=http
        request="index.html"
        receive="A2"
        scheduler=wlc
        persistent=21600 # 6h
        protocol=tcp
        fallback=127.0.0.1:8080/app2/sorry_app2.html

It means, if application1 failed, will the URL "sorry_app1.html" appear to
the user and the URL "sorry_app2.html" will appear in case the application2
failed.

But this is not a valid syntax. Should be just:
fallback = ip_address|hostname[:portnumber|sercvicename]

One possibility could be to configure the local Apache to hear on multiple
ports with different document roots. For example:
#App1
fallback=127.0.0.1:8080 -> document_root: .../app1
#App2
fallback=127.0.0.1:8081 -> document_root: .../app2

In such case will the site "index.html" from different directories appear to
the user.

Any other idea?

Thanks.

Peter

I am not sure that I understand the problem.
I am assuming that you are using ldirectord.
Ldirectord allows you to define a gloabal
fallback server and override this with
per-virtual fallback servers. 

Does this resolve your problem?
If not could you please describe it in more depth.

Thanks
