perform action based on http method.

[clayton-price]

I've not been able to find a way to switch traffic based on http method. For example, I want to essentially drop all http traffic using the TRACE method. I don't think that a header-field with the request-line of "trace" would work. That would seem to apply more to specific content someone was trying to get vs. the http method.

Does anyone know of a way to do what I'm looking for?

Thanks!

the request line should work. To realize that, you must realize that a request line contains something like the following (without the quotes):

"GET /index.html HTTP/1.0"

I tested this real fast in the lab, but sending a redirect instead of dropping, so I could tell it was working, and it worked..

you can configure the following:

!************************** SERVICE **************************

service dummy

ip address 10.10.10.10

keepalive type none

active

!********************* HEADER FIELD GROUP *********************

header-field-group trace-match

header-field .ida request-line contain "TRACE"

!*************************** OWNER ***************************

owner myrule

content block-trace

vip address 2.3.4.5

protocol tcp

port 80

url "/*"

header-field-rule .ida weight 0

add service dummy

active

of course, use your own VIP, instead of 2.3.4.5. Also, you can put a search length on the header-group so you will not catch anyone who puts "TRACE" in the url...

header-field .ida request-line contain "TRACE" 10

let me know if that does the trick or not!

Thanks Steve!

So even if it is not an HTTP GET that they are performing it should work? I'm using header-fields to block nimda and code red etc, but all of those use an HTTP GET instead of HTTP TRACE.

I'll give it a shot.

Thanks!

Clayton,

If they are doing a "GET" then they should not hit the rule with the "TRACE" header field...
