I've been experiencing an issue where editing a wiki page, and then creating a link to an web site (internal to external) does not behave as expected, it takes a number of edit attempts to finally get a working link. I believe this is a bug behavior, as it only takes place when attempting to provide a web link.

Clearing cookies for our internal wiki url in my browser seems to fix it... but I've been clearing cookies for every few months since February 2015 (when our internal Helpdesk jira "HD-16170" was filed)

Two distinct behaviors are seen;

It is not possible to just create the external web link, the save button does not work if I create link, paste in URL for the web link (for example http://www.cloudera.com/documentation/enterprise/latest/topics/cm_sg_guide_ssl_certs.html ) I have to click between the link types, and then come back to the web link (re-pasting the URL) to get the save button to activate.

Once this starts happening, I can no longer create links without cycling through up to 5 save/try to fix/save attempts, before I get a working link. Clearing cookies at this point makes things go away for a bit, but invariably it always returns.
