need to rewrite HTTP 200 status code to HTTP 503
Hello,
I am performing website maintenance and need to bring down our website for a few hours. I will be
serving a friendly maintenance page during this time. However, when Google comes by during the
maintenance period this will present a problem for indexing. I am running BigIP version 10.2.3
Google strongly recommends that we return a 503 HTTP result code during the maintenance window:

downtime.html
There are similiar posts to mine in these forums, but none resolve what I am trying to do. I want to
serve a maintenance page from a pool in VIP and have the F5 rewrite the result code from a 200 to a 503.
I am able to apply the iRule to the VIP, however, it does not serve my maintenance page. This is my
iRule:
when HTTP_REQUEST {
HTTP::respond 503 noserver Retry-After: 10800
}
Thanks,
- Richard__HarlanHistoric F5 AccountWhat version are you running? The HTTP::header should be able to run the the HTTP_REQUEST_SEND event.
- jasona_40790NimbostratusI am running version 10.2.3 Build 112.0. The iRule correct re-writes from HTTP 200 to 300 without this line:
- Richard__HarlanHistoric F5 AccountOk let me test this out on my virtual LTM and see if I can get around this.
- Richard__HarlanHistoric F5 AccountOk I am a idiot there is two issues first HtTP_REQUEST_SEND should allow you to change headers but I think we have to be in server side context. The main problem is I told you to put the HTTP::header in HTTP_REQUEST_SEND. This is the event right before the LTM sends the request to the server side proxy. So this is the request to the server. When you need to change the response to the client. I fix the rule and ran it though some test and it seem to work and change the header. Again sorry for flipping the events

- Richard__HarlanHistoric F5 AccountIf you want to change more data then you would have to do the following. Note it will over write more of the page from the pool member
