asp.net web api - Sitecore and caching control -


i working on sitecore project , using webapi perform service calls. methods decorated cacheoutput information this:

[httpget] [cacheoutput(clienttimespan = 3600, servertimespan = 3600)]

i testing these calls using dhc app on google chrome. sure clienttimespan set correctly response headers getting not expecting. expect cache-control have max-age of 1hour set clienttimespan attribute instead set private. enter image description here have been debugging possible , t turns out sitecore may intercepting response , setting header value private. have added service url sitecore ignored url preffixes configuration no .

anyone has idea how can make sitecore not change cache-control headers?

this default mvc behaviour , not directly related sitecore / web api.
can create custom attribute sets cache-control header:

public class cachecontrol : system.web.http.filters.actionfilterattribute {     public int maxage { get; set; }      public cachecontrol()     {         maxage = 3600;     }      public override void onactionexecuted(httpactionexecutedcontext context)     {         context.response.headers.cachecontrol = new cachecontrolheadervalue()         {             public = true,             maxage = timespan.fromseconds(maxage)         };          base.onactionexecuted(context);     } }

which enables add [cachecontrol(maxage = n)] attribute methods.
code taken from: setting http cache control headers in webapi (answer #2)

or can apply globally throughout application, explained here: http://juristr.com/blog/2012/10/output-caching-in-aspnet-mvc/
