IRules causing certain browsers to crash

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?
