The <iframe> tag is used in HTML to embed a 3rd party website within another HTML webpage.
eKashu supports being used within an iFrame so long as both Cookies and JavaScript are supported within an iFrame. By default, most web browsers have this functionality enabled however certain web browsers can have strict security settings which block any third party Cookies. Therefore, if the content within the iFrame is provided from a different domain, the web browser will automatically block that 3rd party page from loading.
Please note: Due to the Safari browser's cookie policy, using the Hosted Payment Page in an iFrame may cause issues out of our control due to 3rd party Cookies being blocked. Other browsers are following this trend including Google Chrome.
