Hello JRahm, Thanks for your response.
What I want to do is the second one as you mentioned.
I have tried 'html content' with this article https://support.f5.com/csp/article/K99872325, it doesn't work. It seems that 'html content profile' is only for modify HTML content sent in responses from the back-end servers.
What I want is to modify the request . Do you have any suggestion about that?
By the way, the request is in the format xml SOAP as below:
<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">
<Body>
<cardsData>
<card>
<expDate>[string]</expDate>
<pan>
<plainPan>[string?]</plainPan>
</pan>
</card>
<card>
<expDate>[string]</expDate>
<pan>
<plainPan>[string?]</plainPan>
</pan>
</card>
can exist serveral cards
</Body>
</Envelope>
Thank you in advance.
