HTTP header corruption occurs after insertion/modification using an iRule in HTTP Headers which contain mixed end-of-line markers <CRLF> and <LF>.
Inserted headers get concatenated in such a way that the HTTP request header gets corrupted.
- HTTP virtual server - An iRule, policy or profile inserts an HTTP Request header - Such as x-forwarded-for - An HTTP request contains some lines that end with <CRLF> and some that end with <LF>
Use HTTP headers with proper end-of-line markers in compliance with HTTP RFC
