During an RDF Data Access WG meeting http://www.w3.org/2001/sw/DataAccess/ftf1#tech-survey somebody pointed out this bit of the HTTP spec: "We note one exception to this rule: since some applications have traditionally used GETs and HEADs with query URLs (those containing a "?" in the rel_path part) to perform operations with significant side effects, caches MUST NOT treat responses to such URIs as fresh unless the server provides an explicit expiration time." -- http://www.w3.org/Protocols/rfc2616/rfc2616-sec13.html#sec13.9 Perhaps it's worth noting near... "HTTP GET is safe; i.e., agents do not incur obligations by following links." -- http://www.w3.org/2001/tag/doc/whenToUseGet.html -- Dan Connolly, W3C http://www.w3.org/People/Connolly/
