asp.net - How to set different Cache expire times for Client and Server caches -



asp.net - How to set different Cache expire times for Client and Server caches -

i have pages have 10 min cache clients , 24 hours server. reason if page changes, client fetch updated version within 10 minutes, if nil changes server have rebuild page 1 time day.

the problem output cache settings seem override client settings. here have setup:

custom actionfilterattribute class

public class clientcacheattribute : actionfilterattribute { private bool _noclientcache; public int expireminutes { get; set; } public clientcacheattribute(bool noclientcache) { _noclientcache = noclientcache; } public override void onresultexecuting(resultexecutingcontext filtercontext) { if (_noclientcache || expireminutes <= 0) { filtercontext.httpcontext.response.cache.setexpires(datetime.utcnow.adddays(-1)); filtercontext.httpcontext.response.cache.setvaliduntilexpires(false); filtercontext.httpcontext.response.cache.setrevalidation(httpcacherevalidation.allcaches); filtercontext.httpcontext.response.cache.setcacheability(httpcacheability.nocache); filtercontext.httpcontext.response.cache.setnostore(); } else { filtercontext.httpcontext.response.cache.setexpires(datetime.utcnow.addminutes(expireminutes)); } base.onresultexecuting(filtercontext); } }

web config settings

<outputcachesettings> <outputcacheprofiles> <add name="cache24hours" location="server" duration="86400" varybyparam="none" /> </outputcacheprofiles> </outputcachesettings>

how i'm calling it:

[outputcache(cacheprofile = "cache24hours")] [clientcacheattribute(false, expireminutes = 10)] public class homecontroller : controller { [...] }

but looking @ http header shows:

http/1.1 200 ok cache-control: no-cache pragma: no-cache content-type: text/html; charset=utf-8 expires: -1

how can implement properly? asp.net mvc 4 application.

you need implement own solution server side caching , client side caching either utilize clientcacheattribute or outputcache. here reason why require custom solution server side cache.

clientcacheattribute sets cache policy response.cache type of httpcachepolicybase and built-in outputcache sets cache policy response.cache

here i'm trying highlight we don't have collection of httpcachepolicybase have 1 object of httpcachepolicybase can't set multiple cache policy given response.

even if can set http cacheability httpcacheability.serverandprivate 1 time again run in other issue cache duration (i.e. client 10 min & server 24 hours)

what suggest utilize outputcache client side caching , implement own caching mechanism server side caching.

asp.net asp.net-mvc caching outputcache

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
