[squid-users] icap adaptation chains with adaptation sets

[Klaus Brandl]

Thanks!

An other, maybe easier way were to support more then one
adaptation_access lines, so we could do something like this:

adaptation_access pool1 allow all
adaptation_access pool2 allow all

But this is currently not working, only the first line takes effect,
the second is ignored. The config reference says here:

It is currently not possible to apply more than one adaptation
service at the same vectoring point to the same HTTP transaction.

What a shame :)
