redirect base on HTTP header

We have been talking about adding a feature to make POST field extraction a little bit easier but for now you will have to do an HTTP::collect and use the HTTP::payload command to access and parse the data.

Thanks for your reply. Let me explain our existing rules and what I am trying to achieve:

 

 

Existing rules:

 

-------------------------

 

when HTTP_REQUEST {

 

if { [active_members servpool1] == 1 } {

 

log "pool1 is up"

 

set uri [HTTP::uri]

 

log "the initial http uri is: $uri"

 

if { $uri starts_with "/logon\.mic" } {

 

set new_uri [string replace $uri 0 10 /mic/SignIn.mic]

 

HTTP::uri "$new_uri"

 

pool servpool1

 

log "The replaced URL is: $new_uri"

 

}

 

elseif { $uri starts_with "/ea/" } {

 

set new_uri [string range $uri 3 end]

 

log "the new URI is: $new_uri"

 

HTTP::uri "$new_uri"

 

pool servpool1

 

log "the new HTTPURI is $new_uri"

 

}

 

}

 

 

This is what we want to achieve:

 

 

1: We want to retrive a post field named "data" from the initial request from the client

 

2: then set the new_uri variable to :

 

set new_uri [string replace $uri 0 10 /mic/SignIn.mic?data=$data]

 

where $data is the post field retrieved from the client request.

 

 

 

How can we do that?

 

 

Thanks,

You would need to run HTTP::collect when you detect that you are dealing with the form. Then in the HTTP_REQUEST_DATA event, you need to search for the field and can then rewrite the uri to include the data. Try searching for collect and HTTP_REQUEST_DATA to see some examples of collecting HTTP payload.
