Combining iRules for maintenance page with 503 code

Bhattman and nitass,

 

 

Thanks for the responses! As a result I have come up with the following which does seem to be working (I built a test pool out of Cisco switches with http enabled which I disable for the test):

 

 

when HTTP_REQUEST {

 

if { [active_members F5_LB_Switches] < 1 } {

 

switch -glob [string tolower [HTTP::header User-Agent]] {

 

"*scooter*" -

 

"*slurp*" -

 

"*msnbot*" -

 

"*fast-*" -

 

"*teoma*" -

 

"*googlebot*" {

 

HTTP::respond 503 content "" noserver

 

return

 

}

 

}

 

 

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

 

"/" { HTTP::respond 200 content [ifile get f5maint_txt] }

 

"/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

 

}

 

}

 

}

 

}

 

 

Using curl with the User-Agent string with the bot names does come back with a 503 like I want. If you have another minute, please let me know if you see any major flaws.

 

 

Thanks!
