I'm using cisoc-ASA-software version 8.4 and smartfilter. i'm getting "HTTP Error 403 - Forbidden" with below situation.
1) when smartfilter blocks the client url request and sent a block page to the asa box, asa box should forward this to client browser. but asa box sending
"HTTP Error 403 - Forbidden" error message to client browser.
reason may be, block page is exceeding the limit of 3072 bytes.
2) because of this reason, smartfilter is encoding the block page into gzip or deflate and sent to asa box. now the block page size is with in the limit.but in this case also cisco asa is sending it's own error message of , "HTTP Error 403 - Forbidden".
Please help me to configure the cisco -asa such way that it should forward the block page as it is from smartfilter.
