NimbostratusMaintenance/sorry page with image on v11.1
I have written maintenance pages in the past with ease. The examples Devcentral were very helpful. The problem with creating one now that I find are the "iFiles" introduction in v11.
The way we used to do it is this:
"when HTTP_REQUEST {
Check active members of pool, if 0 respond with Apology Page.
if { [active_members your_pool] == 0 } {
HTTP::respond 200 content {
Apology Page
We are sorry, but the site you are looking for is temporarily out of service
If you feel you have reached this page in error, please try again.
}
}
}
"
To get a logo in the html, we just had to put it in a path and call it out. With iFiles, I understand, we call it with the "HTTP::response" 200 command. Since I already use it to create the html page, it seems I cant use it again for the logo picture call. I created this iRule for the new sorry page:
"when HTTP_REQUEST {
Set global variables.
set VSPool [LB::server pool]
set logo [ifile get logo.png]
Check for active members in the associated pool and respond with html content when the pool members are less than 1
if { [active_members $VSPool] < 1 } {
HTTP::respond 200 content {

}"
I have tried to call the "$logo" variable inside of the html as well as the "[ifile get logo.png]" command but it doesnt work. I even tried to add an "IF" statement before the html "IF" but all it does then is show the logo, no text.
ideas?

For those interested, I wrote this up a while back:

pawel_jakacki_7Hi Guys,
is there any possibility to make a such maintenance page using css? I've tried, but with no success.
when HTTP_REQUEST {
if {[active_members [LB::server pool]] < 1} {
if {[HTTP::uri] eq "/"} {
HTTP::respond 200 content [ifile get "index"]
} elseif {[HTTP::uri] eq "/file1.gif"} {
HTTP::respond 200 content [ifile get file1"]
} elseif {[HTTP::uri] eq "/style.css"} {
HTTP::respond 200 content [ifile get "style"]
} elseif {[HTTP::uri] eq "/file2.jpg"} {
HTTP::respond 200 content [ifile get file2"]
} elseif {[HTTP::uri] eq "/file3.jpg"} {
HTTP::respond 200 content [ifile get "file3"]
} else { discard }
}
}
File1 is directly referenced in the index.html and is displayed correctly, other files have reference in style.css file, which has no effect.

Paul, if you're receiving the CSS file, I would put log statements throughout to see what or if the CSS-referenced objects are being called. - pawel_jakacki_7I've moved css into index.html file, and it works smoothly but only in Internet Explorer, in Firefox I'm receiving raw html file. Do you have any idea how to fix it?
- Kevin_StewartAt the end of each HTTP::respond command, add the appropriate content-type header:
HTTP::respond 200 content [ifile get "file3"] "Content-Type" "image/jpeg" - pawel_jakacki_7thanks Kevin, it helps.

I used the example above and it works...but it only works if the user is going to the home page. I'm not a web guy so bear with me, but what I'm trying to say is that if the user goes to:
and the site is down it redirects it to the apology page.
But if the user goes to www.site.com/site/default.aspx then it doesn't redirect. Is there a way to make it so if the user goes to "any" URL within the site that it will redirect to the apology page? I can actually make that work using a basic apology page, but I can't get it to work with this example that uses the ifile to call the image.
What I can get to work is:
...but that doesn't allow me to display an image.when LB_FAILED { if { [active_members [LB::server pool]] < 1 } { HTTP::respond 200 content [ifile get "sharepoint_apology"] } else { discard } }What I'm currently using is:
Thanks,when HTTP_REQUEST { if {[active_members [LB::server pool]] < 1} { switch [HTTP::uri] { "/" { HTTP::respond 200 content [ifile get "sharepoint_apology"] } "/sharepoint_apology_pic" { HTTP::respond 200 content [ifile get "sharepoint_apology_pic"] } } } }David
Dmitriy_SysoevHi! You need to tell browser what is the content of your files. My examples: when HTTP_REQUEST { if { ([active_members /E_Click/clk2_app]) < 1 || ([active_members /E_Click/clk2_login]) < 1} { switch [string tolower [HTTP::uri]] { "/facebook.png" { HTTP::respond 200 content [ifile get "facebook.png"] "Content-Type" "image/jpeg" } "/link_separator.gif" { HTTP::respond 200 content [ifile get "link_separator.gif"] "Content-Type" "image/gif" } "/logo.gif" { HTTP::respond 200 content [ifile get "logo.gif"] "Content-Type" "image/gif" } "/logo2.gif" { HTTP::respond 200 content [ifile get "logo2.gif"] "Content-Type" "image/gif" } "/logo3.gif" { HTTP::respond 200 content [ifile get "logo3.gif"] "Content-Type" "image/gif" } "/logo4.gif" { HTTP::respond 200 content [ifile get "logo4.gif"] "Content-Type" "image/gif" } "/offline_click.jpg" { HTTP::respond 200 content [ifile get "offline_click.jpg"] "Content-Type" "image/jpeg" } "/ppl.jpg" { HTTP::respond 200 content [ifile get "ppl.jpg"] "Content-Type" "image/jpeg" } "/t.gif" { HTTP::respond 200 content [ifile get "t.gif"] "Content-Type" "image/gif" } "/twitter.png" { HTTP::respond 200 content [ifile get "twitter.png"] "Content-Type" "image/png" } "/vkontakte.jpg" { HTTP::respond 200 content [ifile get "vkontakte.jpg"] "Content-Type" "image/jpeg" } "/" { HTTP::respond 200 content [ifile get "click_not_available.htm"] "Content-Type" "text/html" } } } else { HTTP::respond 302 Location "https://xxxxxxxxxx.ru/" } }
BrandonDoes anyone know if there is a limit on characters on maintenance page. If images can be used.

File size limit: I remember reading 4Mb.
Getting the apology page for all pages instead of just "/": instead of "/" in the switch, make that clause the default; or instead of "/" in an "if" test, make that the final "else".
