what version ?? 7.xx(xxx) or 8.xx(xxx) ?


You should capture a sniffer trace on frontend and backend.

Get a trace with the CSS and without and compare the 2 to see where is the difference and which device is at fault.


If you can't see a difference or need assistance understanding the trace, send it to us.

Hi giles,

I am running 8.20 code and the issue is we use bank application and login will be successful and when the transaction is over when i do logout it doesnt give me the msg saying logout is successful were as it logout and prompt me the login page again.


I loked at the los and found that the referer is null when connected through the vip. HTTP request will have the value of null which is causing this issue.


Kindly let me know what do you think about this.


My config is very simple:



ip redundant-vip 172.16.23.3


service bank

ip address 192.1.1.12

protocol tcp

port 443

active


owner data

content me

protocol tcp

vip address 172.16.23.3

port 443

add service bank

application ssl

advanced-balance ssl

sticky-inact-timeout 50

active


Thanks in advance.

We need the complete version 8.20(????)

And a sniffer trace will be usefull to see what is happening.

Hi Giles,

sg0820201.

No sniffer traces available as of now. What I am now looking is referer being stripped out http header. Can you tell me how to set to remove or block the http referer info?


Thanks in advance.

Sum.

Sum,


The CSS NEVER removes the content of HTTP traffic.

We don't even look into the http content.

Hi Giles,

I looked at the traces but there is nothing much present as the connection works and everything is working fine as it should be but only the problem when i click the logout button of the banking site I get page cannot be displayed this is strange.
