I think you need to post the entire iRule instead of just the top. I agree with hoolio that there is a brace missing somewhere, but we won't be able to tell unless we see the entire thing.

if { [HTTP::method] equals "GET" } {
set ToCache 1
if { not ([findstr $ParsedURI "jsessionid"] eq "") } {
set LeftNewURI [substr $ParsedURI 0 ";" ]
set RightNewURI [findstr $ParsedURI "?"]
set NoJsessionID [concat $LeftNewURI$RightNewURI]
set NewURI $NoJsessionID

if {$LeftNewURI eq "/portal/pi/html/search.jsp"} {
set ToCache 0
set Cas 1
}

if { [matchclass $::PageIDNoCache contains $ParamPageID]} {
if {($ParamPageID eq "contacts") and ($ParmaAction eq "local")}{
set NewURI $ParsedURI
}
set ToCache 0
set Cas 2
}
if { not([findstr $ParsedURI "redirect.jsp"] eq "") } {
set MyRedir [string map -nocase {%3a : %3f ? %3d = %26 & %23 } $MyPath]
set ToCache 0

}
if { $ToCache eq "1" } {
CACHE::enable
set ToCache "yes"
}
else {
CACHE::disable
set ToCache "no"
}
if {$MyRedir eq ""}{ 
log local0.info "-- Cas= $Cas -- Cache=$ToCache -- MyRedir=$MyRedir -- URI -- $NewURI"
HTTP::uri $NewURI 
}
else {
log local0.info " -- MyRedir=$MyRedir -- Cas= $Cas -- Cache=$ToCache -- URI -- $NewURI"
HTTP::redirect $MyRedir
}
}
}
}
when HTTP_RESPONSE {
  set monType [HTTP::header "Content-Type"]
  if { [HTTP::header "Content-Type"] equals "text/a.wml" } {
    log local0.info " Content - $monType -- NO CACHE"
    CACHE::disable
  }
 else {
  log local0.info " Content -- $monType -- CACHE"

}

When I first looked at this, I thought you were missing a brace to close the HTTP_REQUEST event. But I think the problem is with this statement:

set MyRedir [string map -nocase {%3a : %3f ? %3d = %26 & %23 } $MyPath]

Also, I think I've had cases where the iRule editor has accepted code that was not accepted by the admin GUI. I tend to trust editing iRules in the admin GUI more than the editor.

            else {
                log local0.info " -- MyRedir=$MyRedir -- Cas= $Cas -- Cache=$ToCache -- URI -- $NewURI"
                HTTP::redirect $MyRedir
            }    
        }
    }
}
}
when HTTP_RESPONSE {
  set monType [HTTP::header "Content-Type"]
  if { [HTTP::header "Content-Type"] equals "text/a.wml" } {
    log local0.info " Content - $monType -- NO CACHE"
    CACHE::disable
  }
 else {
  log local0.info " Content -- $monType -- CACHE"
 }
}
