Large CSS files configured for phishing protection injection in FPS may be truncated upon response to client.
Pages may display incorrectly in client browser depending on application requirements with specific CSS. Application functionality might not work as expected.
-- Inject into Application CSS enabled in Anti-Fraud Profile :: Advanced :: Phishing Detection. -- Large CSS file such as bootstrap files configured for Application CSS Locations. -- Network congestion engaging TMM flow control.
You can use either of the following workarounds: -- Remove affected large files from Application CSS Locations. -- Disable Inject into Application CSS entirely.
FPS now handles the case where injecting to application CSS is interrupted by congestion.
