asp.net mvc - Why are my images not cached although I configured OUTPUTCACHE? -


so, trying configure caching mvc5 application optimization purposes. although put outputcache attribute on controller action method can't see images cached. here controller action:

[outputcache(duration = 60, location = outputcachelocation.serverandclient, nostore=true, varybyparam = "resultid")] public filecontentresult getpicture(string resultid) {    var actionlinks = db.actionlinks.tolist();    var actionlinkpic = actionlinks.firstordefault(p => p.id == resultid);    if (actionlinks != null)    {       return file(actionlinkpic.tpicture, actionlinkpic.tpicturemimetype);    }    else    {       return null;    } }

here network response in firefox:

the network response:

enter image description here

you have nostore=true

the nostore property disables caching - commonly used disable caching requests (which cached default).

change nostore=false

unfortunately there little documentation outputcacheattribute, extent have experiment options, , see happens.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
