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

Workaround

Use an iRule to correct erroneously rewritten URLs.

Fix Information

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