iRule stopped working with upgrade to 9.4.1

I have more information, thanks to a reproduction that I put together. I stripped out the pool selection parts, and just focussed on the translation parts.

 

 

I put a file named test.aspx on an internal web server, and pointed a virtual server at it with the iRule applied.

 

 

When I requested test.aspx from the webserver, it is returned as we would expect.

 

 

If I request test.ospx from the virtual server, I get a 404 Not Found from the Web Server.

 

 

If I request test.aspx from the virtual server, I get the page with all the aspx translated to ospx

 

 

So it would appear that STREAM::expression works just fine. What is broken is this part:

 

 

when HTTP_REQUEST {

 

set uri [HTTP::uri]

 

if { [string tolower [HTTP::uri]] contains ".osp" } {

 

replace remote_addr with .ospx -> .aspx and .osp -> .asp

 

set uri [string map -nocase {.ospx .aspx .osp .asp} $uri]

 

 

Set target uri to the version after the replaces have been run

 

HTTP::uri $uri

 

}

 

 

}
