Blue Coat Systems Proxy SG manual Definitions define action, define activecontent

ProxySG Content Policy Language Guide

•server_url_substring—A string that, if found in the server URL, will be replaced by the client_url_substring. The comparison is done against original normalized URLs embedded in the document.

Note: Both client_url_substring and server_url_substring are literal strings. Wildcard characters and regular expression patterns are not supported.

Discussion

If there are a series of subst_embedded and subst_prefix statements in a url_rewrite definition, the first statement to match a URL takes effect and terminates processing for that URL.

Layer and Transaction Notes

Applies to proxy transactions.

<Proxy> ; server portal for IJK url=ijk.com/ action.ijk_server_portal(yes)
