Hi,

i have the below irule but if any cap "uri" will not redirect correctly. I appreciate any though or input, thanks a lot.

 

1- this uri will redirect but not correctly https://www.abc.com/App/topic/Topic.aspx?topici=90 => https://www.xyz.com/app/Topic/Topic.aspx?topici=90

2- this uri will redirect but not correctly https://www.abc.com/app/Topics/Topic.aspx?topicid=128 => https://www.xyz.com/app/Topics/Topic.aspx?topicid=128

3- this uri will redirect correctly https://www.abc.com/app/topic/Topic.aspx?topici=128 => https://www.xyz.com/redirectlegacy/abc/app/topic/Topic.aspx?topici=128

4- this uri will redirect correctly https://www.abc.com/app/topic/topic.aspx?topici=122 => https://www.xyz.com/redirectlegacy/abc/app/topic/topic.aspx?topici=122

 

when HTTP_REQUEST {  

  if { ([string tolower [HTTP::host]] eq "www.abc.com") and ([string tolower [HTTP::uri]] starts_with "/app/topic/") } {

    HTTP::redirect "https://www.xyz.com[string map {/app/topic/ /redirectlegacy/abc/app/topic/} [HTTP::uri]]"

  }

}

Hi,

 

string tolower command does not convert HTTP::uri to lowercase but returns lowercase of HTTP::uri

 

So even if it matches the condition  :

{ ([string tolower [HTTP::host]] eq "www.abc.com") and ([string tolower [HTTP::uri]] starts_with "/app/topic/") }

 

[string map {/app/topic/ /redirectlegacy/abc/app/topic/} [HTTP::uri]] will work with original HTTP::uri value.

 

you should change the code to this one to returns lowercase uri

 

when HTTP_REQUEST { if { ([string tolower [HTTP::host]] eq "www.abc.com") and ([string tolower [HTTP::uri]] starts_with "/app/topic/") } { HTTP::redirect "https://www.xyz.com[string map {/app/topic/ /redirectlegacy/abc/app/topic/} [string tolower [HTTP::uri]]]" } }
