replace IP in POST body with source IPaddr

Hi RZ,

 

 

As I mentioned before, I don't think a stream profile/iRule will work for rewriting request payloads where the search and replace string are different lengths. The reason for this is that there is no way to update the Content-Length header. So the rewritten request payload won't be valid.

 

 

If you use HTTP::collect and HTTP::payload, LTM will update the Content-Length header for you.

 

 

Also, the reason [IP::client_addr] isn't working is that the curly braces prevent interpretation of variables and commands. This would allow variable expansion:

 

 

set client_ip [IP::client_addr]

 

STREAM::expression [subst -nocommands {@\"xsd:string\">\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}@"xsd:string">$client_ip@}]
