SOAP Response New to F5 - iRules

Hi Duffy,

You can use HTTP::respond to send an LTM generated HTTP response.

http://devcentral.f5.com/wiki/default.aspx/iRules/http__respond

Here is an example:

HTTP::respond 200 content {http://www.w3.org/2005/08/addressing/soap/fault urn:uuid:318bb7b9-8ca6-4f9c-a094-a82f82109fc1 s:Sender The application is temporarily down for maintenance. " } noserver Cache-Control private Content-Type {application/soap+xml; charset=utf-8} Server {Microsoft-IIS/7.5}

If you're on 9.4.1 or lower, you won't be able to use the noserver flag to suppress the LTM inserted "Server: BigIP" header in responses.

To check if the pool has no active members, you can use active_members:

when HTTP_REQUEST {
   if {[active_members [LB::server pool]] == 0 }{
      HTTP::respond 200 content \
         {http://www.w3.org/2005/08/addressing/soap/fault urn:uuid:318bb7b9-8ca6-4f9c-a094-a82f82109fc1 s:Sender The application is temporarily down for maintenance. " } \
         noserver \
         Cache-Control private \
         Content-Type {application/soap+xml; charset=utf-8} \
         Server {Microsoft-IIS/7.5}
   }
}
