You're right there's a "Cache-Control: no-cache".
     1	GET xxxxxxxxxx HTTP/1.1
     2	Content-Type: application/x-www-form-urlencoded
     3	Keep-Alive: 300
     4	User-Agent: xxxxx
     5	Host: xxx.xxx.xxx.xxx
     6	Cache-Control: no-cache

What I'm trying to do is have DeleGate cache for everything
transparently independant of the client. I thought about filtering out
"Cache-Control: no-cache" with HTTPCONF but that only modifies the
header and not how DeleGate functions.

I got it to work by using 2 HTTP proxies. The 1st one would just
filter out Cache-Control and then the 2nd would do the actual work.
Seems like a good idea for DeleGate to use the headers it modifies
though.

delegated -P8080 SERVER=http CACHE=do ADMIN=y
HTTPCONF=kill-qhead:Cache-Control FCL="-tee-h-n"
ROUTE="http://localhost:8081-_-{*:80}" -vd

delegated -P8081 SERVER=http CACHE=do ADMIN=y FCL="-tee-h-n" -vd

I also tried using CFI but that just messed things up.
#!cfi
Remove/Cache-Control: no-cache

I'm just wondering if there's a better way than using HTTPCONF and 2 proxies.

Thanks.
