Best approach to serve maintenance page
Hi, We need to put website under maintenance for about 6 hours. Traffic flow: Clients -->Akamai--->F5-->Backend servers. We have maintenance page hosted in AWS cloud Front. which approach is better? DNS Change – Temporarily point our domain (via CNAME) to CloudFront by adjusting the TTL to 2 minutes. F5 Configuration – Issue a 302 redirect from F5 to CloudFront or forward (reverse proxy) traffic from F5 to CloudFront by modifying the Host header. This keeps the browser on our domain and returns a 200 OK. Main concerns : Avoiding browser/edge caching issues (we can clear Akamai cache if needed). Ensuring a quick rollback after maintenance. Which approach would be best? Could you advise on the correct implementation?
irule maintanance page issue
Can anyone out there tell me what could be wrong with this code for an irule to reference HTML for a maintance splash page? when HTTP_REQUEST { if { [active_members [LB::server pool]] == 0 } { check if client access from internal subnet if { [IP::addr [IP::client_addr]/8 equals 10.0.0.0] } { pool alternate_pool } else { HTTP::respond 200 content { Sorry Page Sorry, The website is not available. Please try again later } } } I am losing my mind over trying to figure it out. it is giving me a missing bracket error and when I input it into notepad++ it isn't showing any error. here is the errors it is giving me 01070151:3: Rule [/Common/test_maintanance] error: /Common/test_maintanance:1: error: [parse error: missing close-brace][{ if { [active_members [LB::server pool]] == 0 } { check if client access from internal subnet if { [IP::addr [IP::client_addr]/8 equals 10.0.0.0] } { pool alternate_pool } else { HTTP::respond 200 content { Sorry Page Sorry, The website is not available. Please try again later } } }] /Common/test_maintanance:2: error: [command is not valid in the current scope][if { [active_members [LB::server pool]] == 0 } { check if client access from internal subnet if { [IP::addr [IP::client_addr]/8 equals 10.0.0.0] } { pool alternate_pool } else { HTTP::respond 200 content { Sorry Page Sorry, The website is not available.
