IRule for Context-Specific ASM Error Page

Aaron,

 

 

Thanks for the response. The change you submitted doesn't work unfortunately -- it results in connection resets for some reason. As for the PHP code, I'm not showing any of the parameters on the page, except for support ID which I am sanitizing.

 

 

I just tried changing the Redirect URL loaded in the ASM to an empty value, which actually fixed Chrome. This took some doing, since the javascript validation in the F5 wouldn't let me submit it at first. So I used the tamper data firefox extension to change the data after it passed validation, the ASM never bothers to validate it server-side, so I was able to get it to save.

 

 

This fixed Chrome, but for some weird reason, IE now redirects to:

 

 

http://www.domain.com/not_found.htm?filterId=259203436710356052&uri=/

 

 

It looks like IE follows the first redirect and then follows the empty one, which it interprets as a request for the document root on the current domain. So close...

 

 

Any other suggestions? Can I try disabling the ASM's rejection of the request somehow and rely on my own redirect to handle the request?
