Opened: Apr 07, 2015

Severity: 3-Major

Symptoms

Safari, Chrome, Edge and Internet Explorer support backslashes in URL path and treat them as slashes. But Portal Access converts backslashes in URLs to slashes explicitly; this may cause unexpected results in some web applications. Note that FireFox has no such support.

Impact

Web application may not work correctly.

Conditions

HTML page with URL with backslashes in the path, for example: <a href=http://some.com\some\path/file.ext>

Workaround

In some cases it is possible to modify rewritten URLs by iRule.

Fix Information

Now URLs with backslashes are supported correctly by Portal Access for all browsers except for Internet Explorer 7--9 and FireFox.
