How to do?

we running A1 code on our Ace

We have seen this with all languages using non-ascii characters.

Your web browser should normally encode those characters as they are illegal per RFC.

Those characters have been allowed with the following ddts :

CSCsm89835: Accept not encoded characters after a ? inside url

Go to the latest A2(1.3) version or A3(2.1) if you have an appliance.

You are probably hitting

CSCsh38439

Have you tried using different browsers?

Is the result same for all browsers.

I have seen that IE normally messes up with the special characters.

I don't know if this bug is affecting me, in the below example towards the end of the link it's that swedish language characters that gets dropped by ACE. Is anyone else experiencing something similar?

Hi Gilles,

I have now upgraded to A2(2.0) and the problem with the static html pages went away, but now I have another problem with links from a webpage to pdf files that have both spaces and internationel characters in the file name?

Anyone else having the same problem?

I'd just like to add that the workaround for this was to do loadbalancing on layer 3 source addresses which is not very scalable

ie. class-map type http loadbalance match-any FBJACK

3 match source-address 10.0.0.0 255.252.0.0

4 match source-address 172.22.0.0 255.255.224.0
