65,000 character limit in irule and URI redirects

Hi all, I've been asked to do something and the way I thought I could do it isn't working (and probably isn't the best way to go about it) We have 2 domains (domain1.net.com an domain2.org.info). ...

An update to this.

I've created the data group. The information looks like this

 

"unique/uri/is/here" := "https://www.domain2.net.org/unique/uri/goes/here",

 

That goes on for about 1000 rows. I saved it as a CSV file in notepad.

I uploaded that file to the F5 as per https://support.f5.com/csp/article/K73862425. I created the Data Group File List as a name like DGNAME.TXT, chose String as the File Contents and the Key Seperartor as :=. The file imported ok

 

I then created the External Data Group and named it NAMEHERE and chose the DGNAME.TXT file I uploaded

 

The problem I have now is getting the iRule to work. I've looked at a few options but none seem to work. This is my latest iRule

 

 

when HTTP_REQUEST {

   if { [class match [HTTP::uri] contains "NAMEHERE"] } {

  HTTP::respond 301 location "https://[HTTP::host][class lookup NAMEHERE]"

   }

 }

 

I'm unable to get anything to happen and the page times out.

 

Any ideas would be appreciated

 

Thanks

    You need

    when HTTP_REQUEST {
   if { [class match [HTTP::uri] contains NAMEHERE] } {
     HTTP::respond 301 location "[class match -value [HTTP::uri] contains NAMEHERE]"
   }
}
