Rechunk profile and string replacement -> pages truncated

Hi,

 

 

I've created an Irule which deals with many string replacement within HTTP_RESPONSE on a re-chunk profile virtual server. We are using BIG-IP 9.3.1 Build 37.1.

 

 

It seems working for us but for some of our customers, they got pages truncated. I do not know the reason why but I think the issue may come from the transfer-encoding set to chunked but I'm not sure.

 

 

Here is my irule

 

 

when HTTP_REQUEST {

 

set host [HTTP::host]

 

}

 

 

when HTTP_RESPONSE {

 

if {[HTTP::status] == 200 and [HTTP::header "Content-Type"] contains "text"} {

 

if {$host ends_with ".foo.com"}

 

{

 

STREAM::expression {@'/xxx/@'/yyy/@ @'/zzz@'/uuu@}

 

STREAM::enable

 

}

 

}

 

}

 

 

If you have any idea where is the issue or if I have misconfigured some parameters, thank in advance for your help.

 

 

Regards,

 

 

Nicolas
