IRules causing certain browsers to crash

Crashing a browser is one thing, Giving a "cannot display page" error is another.

 

 

Have you done a packet capture? Is the client receiving a RST from the Server (through the LTM)?

Sorry, I mean to say "error". Here is what I got from the logs:

 

 

HTTP_REQUEST - Operation not supported. Multiple redirect/respond invocations not allowed line 137 invoked from within HTTP::respond 301 Location [string map {/portal/site } [HTTP::uri]]

 

 

 

We are doing URL masking so it's kind of hard to NOT have multiple redirects. Any thoughts something else to try to prevent this?

 

I continue to do some packet sniffing in the mean time.

Without knowing the full rule, it's a bit difficult. Can you post an anonymized version of your HTTP_REQUEST event and what you're trying to accomplish?

Hello ,

I think it was a combination of too many 301 redirects and where the "return" syntax was placed in the code.

 

 

 

ex)

 

HTTP_REQUEST {

 

.....................

 

if { ([string tolower [HTTP::uri]] contains "site_picker") or

 

([string tolower [HTTP::uri]] contains "create_profile") } {

 

if user does NOT have access to the site, set the portal cookie flag to redirect

 

if it exist

 

if { ([HTTP::cookie exists $::portalCookie]) } {

 

set ::portalExist 1

 

}

 

return

 

} elseif { ([HTTP::uri] contains "/solutioncenter") } {

 

set global variable flag for any old solutioncenter URL to 1

 

and replace site names

 

set ::SC_Flag 1

 

HTTP::respond 301 Location [string map {"/solutioncenter" "/erp"} "[HTTP::uri]"]

 

return

 

} elseif { ([HTTP::uri] contains "+") or ([HTTP::uri] contains "action.process") } {

 

Allow VCM URLs and login actions to go through

 

return

 

 

}

 

..............

 

}

 

 

 

The issue seemed occur when their was ONLY 1 return syntax at the very bottom of the "HTTP_REQUEST" function.

 

I would think it would NOT matter, but from testing, it seems to be case. Any thoughts?
