Symptoms

Incomplete URLs are not taking into account matching rewrite / bypass lists in Split Tunneling mode.

Impact

Incomplete URLs are rewritten in spite of actual bypass list. This may make these URLs invalid or non-functional.

Conditions

- Bypass list that includes 'http://example.com*: any request to matching URLs should not be rewritten. - HTML page with the following URL: <a href='//example.com/'>Link should not be rewritten</a>

Workaround

Use an iRule to correct erroneously rewritten URLs.

Fix Information

Now rewrite / bypass lists are used correctly for incomplete URLs.

Behavior Change

Split Tunneling configuration with non-empty bypass list now requires a non-empty rewrite list as well. For instance, you must add a wildcard rule to the rewrite list: bypass list: "http://example.com*' rewrite list: "http://* https://*"
