URI Redirect

Hi,

 

 

We would like to redirect all traffic to our maintenance page, so far if someone calls the domain name for example "www.domainname.com" the irule works and redirects the person to "www.domainname.com/maintenance.html" If someone calls "www.domainname.com/sitefolder/" the irule will not work. I tried changing it but the irule will just loop.

 

 

when HTTP_REQUEST {

 

if { [HTTP::path] equals "/" } {

 

HTTP::redirect "/maintenance.html"

 

 

 

Thanks

    This is because the you have [HTTP::path] equal "/" which means that it will only redirect when there is no URI in the domain.

    For example this will redirect to maintenance if it matches 2 conditions 

     
 when HTTP_REQUEST { 
    if { ([HTTP::host] eq "www.domainname.com") and ([HTTP::path] eq "/" } { 
    HTTP::redirect "http://[HTTP::host]/maintenance.html" 
    } 
 }

    If you want it to match on "/sitefolder" and "/"then you can do the following 

     
 when HTTP_REQUEST { 
    if {[HTTP::host] eq "www.domainname.com") } { 
    switch -glob [HTTP::path] { 
    "/" { HTTP::redirect "/maintenance.html" } 
    "/sitefolder" { HTTP::redirect "/maintenance.html" } 
    } 
    } 
   }

    You can keep expanding to other URIs as well

    I hope this helps

    Thanks, your rules work but is it possible to put a wildcard for HTTP::path, we dont want users to surf the website.

    or you can do this 

     
  
 when HTTP_REQUEST {  
     if {[HTTP::host] eq "www.domainname.com") } {  
     switch -glob [HTTP::path] {  
     "/" { HTTP::redirect "/maintenance.html" }  
     "/sitefolder" { HTTP::redirect "/maintenance.html" }  
                         default   { HTTP::redirect "/maintenance.html" }  
     }  
     }  
    }

    Basically if doesn't match any of the paths select then the default will always match.

    I get a redirection loop error in Firefox. I also tried "/*" but that does not work for me.

    It would be easier to handle if the maintenance page was in a unique directory. You could then check if the requested path started with that directory before redirecting them. This would avoid a redirect loop: 

     
 when HTTP_REQUEST { 
  
     Check if URI does not start with "/maintenance" 
    if {not ([HTTP::path] starts_with  "/maintenance")}{ 
  
       HTTP::redirect  "/maintenance/maintenance.html" 
    } 
 }

    As log as any files the /maintenance/maintenance.html page references are under the /maintenance/ directory, this should work.
