When web pages are displaying in plain text but with graphics included, it typically indicates that CSS files are not being loaded. CSS (Cascading Style Sheets) are responsible for the styling and formatting of web pages. If the Start URL list does not include CSS files, the Citrix Web App Firewall might be blocking these essential resources, resulting in the web pages rendering in plain text format without proper styling.
Protections that ensure the correct data is returned by the client typically involve checking the consistency and format of data submitted through forms. Form Field Consistency ensures that the form structure is not altered and that the data submitted adheres to set restrictions. Field Formats validate the type and length of user-submitted data to ensure they match the expected formats. These checks help ensure the integrity and correctness of the data returned by the client.
When implementing multi-factor authentication for Citrix Gateway, the custom forms created for capturing user credentials need to be uploaded to the directory /flash/nsconfig/loginschema on the Citrix ADC. This directory is designated for storing custom login schemas, whereas built-in schemas might reside in a different subdirectory. Therefore, the appropriate folder to upload the custom form is /flash/nsconfig/loginschema.
To empty the Learn database for the application firewall, the command 'reset appfw learningdata' is used. This command clears all learning data accumulated for application firewall profiles, enabling the engineer to start fresh when configuring protections for a different web application.
