Usage of via string from Header

Dear All,

since long time we are using the via string from the header within a rule to make a  decision within a rule.

It was implemented with version 7.1.6

Now we started to use 7.3.0.2.0.

And now we can't use more the via string.

Here an example how we have implemented it in a rule:

Header.Request.Get("via") matches *111.111.111.111*

Also if we try to show the via string in a block message now the value is empty.

Does somebody have a solution for this?

Thanks

Re: Usage of via string from Header

I do not see that behaviour on my 7.3.0.2.

I have a rule that blocks on this criteria:

  Header.Request.Get ("Via") matches *192.168.2.232*

And when i forward from another proxy with that IP address, it blocks as it should.

This rule is at the top in only the request cycle, then i have another rule below that in the request/response cycle that removes the Via header as it goes out to the internet.

i don't know why it wouldn't work for you.

Re: Usage of via string from Header

Hello,

thanks for the answer.

To specify this here some more information.

I can see the via information for a normal request but I can't see the via information in context with "next hop proxy".

So I have open a case at McAfee. Let see what they can find out.

Thanks
