Combining iRules for maintenance page with 503 code

Hi Rob,

 

I think I can assist on a portion of this.

 

 

Recall the portion of the code you posted

 

{ [active_members [LB::server pool]] < 1 }

 

 

This should change to

 

{ [active_members pool] < 1] } were "pool" is your pool name

 

 

You can find references to it on the irule code wiki (https://devcentral.f5.com/wiki/iRules.active_members.ashx)

 

 

Also consider using the switch command

 

 

For example you could re-write you code to the following using the switch statement which is more efficient then IF-ELSEIF-ELSE statement

 

 

when HTTP_REQUEST {

 

if { [active_members pool ] < 1] } {

 

log local0. "Server Pool: [LB::server pool]"

 

HTTP::respond 200 content [ifile get f5maint_txt]

 

} else {

 

switch -glob [string tolower[HTTP::uri]] {

 

"/favicon.ico" { HTTP::respond 200 content [ifile get favicon_ico] }

 

"/reset.css" { HTTP::respond 200 content [ifile get reset_css] }

 

"/style_main.css" { HTTP::respond 200 content [ifile get style_main_css] }

 

"/jquery.js" { HTTP::respond 200 content [ifile get jquery_js] }

 

"/jquery.jfeed.pack.js" { HTTP::respond 200 content [ifile get jquery.jfeed.pack_js] }

 

"/head.js" { HTTP::respond 200 content [ifile get head_js] }

 

"/search.js" { HTTP::respond 200 content [ifile get search_js] }

 

"/image_topbarleft.jpg" { HTTP::respond 200 content [ifile get image_topbarleft_jpg] }

 

"/image_topbarright.jpg" { HTTP::respond 200 content [ifile get image_topbarright_jpg] }

 

"/image_navtop.jpg" { HTTP::respond 200 content [ifile get image_navtop_jpg] }

 

"/logo_main.png" { HTTP::respond 200 content [ifile get logo_main_png] }

 

"/image_contactbkg.png" { HTTP::respond 200 content [ifile get image_contactbkg_png] }

 

default { discard }

 

}

 

}

 

}

 

 

 

 

I hope this helps
