Hi,

 

 

Can you post the full rule you're currently testing and a sample of the source data you want to perform the replacement on and what you want it to look like afterwards?

 

 

You can indeed insert more data than was there in the payload to begin with. However, in versions before 9.4.0 (?), you need to set chunking to 're-chunk' in order to have BIG-IP recalculate the content-length correctly.
