set srcIP [IP::client_addr]

 

 

if {$uri equals "/"}

 

{ HTTP::redirect "http://m.srwd32.com/mobile/" }

{$uri starts_with "/myaccountapi/myaccount"}

 

{ persist none

 

pool SRWD32-MYX }

 

else{ if {$uri starts_with "/mobile/auth" and $port != 443 }

 

{ HTTP::redirect "https://[HTTP::host][HTTP::uri]"

if $uri is / go to http://m.srwd32.com/mobile/

 

if $uri starts_with "/myaccountapi/myaccount go to pool SRWD32-MYX

 

if {$uri starts_with "/mobile/auth" and $port != 443 go to https://[HTTP::host][HTTP::uri]

    Hi jucao,

    Try this and see if it works for what you are needing: 

    
when HTTP_REQUEST {
switch -glob [ string tolower [HTTP::uri]] {
"/" { HTTP::redirect "http://m.srwd32.com/mobile/" }
"/myaccountapi/myaccount*" { persist none; pool SRWD32-MYX }
}
if { [[TCP::local_port clientside] != 443] && [[HTTP::uri] starts_with "/mobile/auth"] } {
HTTP::redirect "https://[getfield [HTTP::host] ":" 1]/[HTTP::uri]"
log local0. "here i am 1 [HTTP::uri]"
}
else {
persist none
 SSL::disable serverside
pool SRWD32-STATIC
 log local0. "here i am 2 [HTTP::uri]"
}
}

    Hi Michael,

     

     

    If you click Edit and then Save on your post the ampersands will be rendered correctly.

    Every time I have done that in the past it distorts the formatting of the entire post :-(

    Thanks ,it seems switch works more effective than if.elseif,else,right?

     

     

    Any ,I found issue with this irule ,esle should be put behind },maybe it is sensitive to the } position.

     

    if {$uri equals "/"}

     

    { HTTP::redirect "http://m.srwd32.com/mobile/" }

     

    elseif

     

    {$uri starts_with "/myaccountapi/myaccount"}

     

    { persist none

     

    pool SRWD32-MYX }

     

    else{ if {$uri starts_with "/mobile/auth" and $port != 443 }

     

    { HTTP::redirect "https://[HTTP::host][HTTP::uri]"

     

    log local0. "here i am 1 [HTTP::uri]"

     

    }else

     

    { persist none

     

    SSL::disable serverside

     

    pool SRWD32-STATIC

     

    log local0. "here i am 2 [HTTP::uri]" } } }

    I think the problem is with no spaces before or after the elses:

     

     

    else{ if {$uri starts_with "/mobile/auth" and $port != 443 }

     

    ...

     

    }else

     

     

    If you put spaces before and after the else statements it should load. But yes, the switch statement should be more efficient than the if/elseif/.../else chain.

    Generally speaking we always encourage people to use switch over if/else chains where it makes sense. They're more efficient once you get past only a few if/else comparisons.
