Maintenance page

Hi,

You need to do use something to define what heavy load is.

There's a good bit of code by Hoolio that sets a maximum number of connections which could be used as your heavy load threshold. You could modify this to suit your requirments.

You could serve content from your iFiles instead of the static content in the example.

sorry for not making it clear, there is already a 'code' to define heavy load traffic..

i need some assistance on the if..then statement..

if pool < 0 then load maintenance page, elseif heavy load traffic then load heavy load page. end if

both pages will have the same images (uploaded to ifiles) but just different wordings..

thanks in advance

if pool < 0 then load maintenance page, elseif heavy load traffic then load heavy load page. end if

isn't this if-statement already correct?

i tried the below if statemen and it doesnt work, as in the images wont load.

if { [active_members pool] < 1 } { HTTP::respond 200 content [ifile get maintenance.html] } elseif { highload > 2 } { HTTP::respond 200 content [ifile get highload.html] }

if { [HTTP::uri] eq "/assets/images/companylogo.png" } { HTTP::respond 200 content [ifile get company.png] "Content-Type" "image/png" } elseif { [HTTP::uri] eq "/assets/images/footer.png" } { HTTP::respond 200 content [ifile get footer.png] "Content-Type" "image/png" }

have you tried to swap order of the if-statements?

if { [HTTP::uri] eq "/assets/images/companylogo.png" } { 
  HTTP::respond 200 content [ifile get company.png] "Content-Type" "image/png" 
} elseif { [HTTP::uri] eq "/assets/images/footer.png" } { 
  HTTP::respond 200 content [ifile get footer.png] "Content-Type" "image/png" 
}

if { [active_members pool] < 1 } { 
  HTTP::respond 200 content [ifile get maintenance.html] 
} elseif { highload > 2 } { 
  HTTP::respond 200 content [ifile get highload.html] 
}

just noticed the log.. not sure what it meant..(with my initial code)

TCL error: /Common/ - Operation not supported. Multiple redirect/respond invocations not allowed invoked from within "HTTP::respond 200 content [ifile get companylogo.png] "Content-Type" "image/png""

can you try something like this?

if { [HTTP::uri] eq "/assets/images/companylogo.png" } { 
  HTTP::respond 200 content [ifile get company.png] "Content-Type" "image/png" 
  return
} elseif { [HTTP::uri] eq "/assets/images/footer.png" } { 
  HTTP::respond 200 content [ifile get footer.png] "Content-Type" "image/png" 
  return
}

if { [active_members pool] < 1 } { 
  HTTP::respond 200 content [ifile get maintenance.html] 
} elseif { highload > 2 } { 
  HTTP::respond 200 content [ifile get highload.html] 
}

Thank you very much, it did load the images.. But do you mind to explain what does the return do ?

do you mind to explain what does the return do ?

it does exit from current irule event.

the problem was it is not possible to have multiple response for one request (i.e. request matches two HTTP::respond commands). return helps because it would exit from irule execution after matching HTTP::respond.

thank you so much for your help !
