custom response page no longer working

[seniornwb]

Hi,

Palo Alto 2050 running version 4.1.11

We have had a custom response page that has not been changed since the beginning. Lately the response page no longer works. It doesn't even load. When a user accesses a blocked page it just keeps loading.

When I put back the factory default page all is fine

It might be after a configuration change or a system update.

I traced back the issue to the following line in the body of our custom response page:

<p><h2>Of stuur een mail: <a style="color: #DDDDDD" href="mailto:helpdesk.xxxxxxx@xxxxxx.nl?SUBJECT=vrijgeven%20website%20<url/>&BODY=user%3A<user/>%0D%0Apagina%3A<url/>%0D%0Acategorie:<category/>%0D%0AMotivatie%3A">helpdesk.xxxxxxx@xxxxxx.nl</a></h2></p>

Without this line the response page works, but I am not sure why it suddenly stopped working.

Is there a limit to the length of the customer response page now, or is there a limit to the length of the line, or is there some sort of syntax error in the line, that previous versions of the palo alto processed fine but current versions choke on.

Any help resolving the issue or any tips would be welcome

PAN OS 4.1.11 seems to have an issue with custom response pages over a certain size. A fix is being targeted for PAN OS 4.1.12.

In the meantime, can you please test by lowering the custom page size to somewhere around 1000 bytes?
