Parse errors

There were quite a few mismatched curly and square braces. Also, you need to use the keyword "content" with HTTP::respond. Can you try this? I haven't checked it fully for logic, but it loads at least.

when HTTP_REQUEST {
 logging for debug purposes. The following message in particular will place heavy load on the system. Remove for prod!
log local0.info "processing request for [HTTP::host][HTTP::uri]"
handle the */awdServer/* case.
if {[HTTP::uri] contains "/awdServer/"} {
if the Referer header does not exist this is a hard-bookmarked or malicious request and it will be logged and rejected.
 if { [HTTP::header exists "Referer"] } {
if { [HTTP::header Referer] equals "" } {
log local0.warn "request for [HTTP::host][HTTP::uri] was dropped due to a null Referer header"
HTTP::respond 404 content "Object not found."
return
}

 grab the query string from the Referer header
set ref_uri [URI::query [HTTP::header Referer]]
 grab the Platform from the Referer header query string, if present
if { [URI::query  $ref_uri platform] ne "" } {
set ref_Platform "[URI::query $ref_uri platform]/"
}
 collect the CLIENT value from the Referer header query string, if present.
if { [URI::query $ref_uri client] ne "" } {
set ref_Client [URI::query $ref_uri client]
}
 if there was a host value in the Referer query string, rewrite the Host header
set orig_URI [HTTP::uri]
if { [URI::query $ref_uri host] ne "" } {
set ref_Host [URI::query $ref_uri host]
log local0.info "rewriting Host header [HTTP::host] to $ref_Host"
HTTP::header replace Host $ref_Host
}
rewrite the URI to /PLATFORM/CLIENT/OriginalURI
set awd_uri "/${ref_Platform}${ref_Client}${orig_URI}"
log local0.info "rewriting [HTTP::uri] to ${awd_uri}"
