I'm trying to optimize our pages so they'll load faster. Chrome's "Audit" thing wants me to enable caching. I was able to do so one one page by changing:


Response.CacheControl = "no-cache"
...to...

Response.CacheControl = "private"

However, just about every file in ProductCart has these lines at the top:

<% response.Buffer=true
Response.Expires = -1
Response.Expiresabsolute = Now() - 1
Response.AddHeader "pragma","no-cache"
Response.AddHeader "cache-control","private"
Response.CacheControl = "no-cache"
%>

It seems like AddHeader "cache-control" and CacheControl "no-cache" are redundant. Is there any reason for them both being here? Do they do something different? If I want to enable caching, which one should I change / remove?

Most importantly, will it screw anything up if I enable caching? Worst case scenario I can think of is we remove a product from the storefront or change the price, and a customer sees the old info.]]> Fri, 28 Feb 2014 23:57:41 +0000 https://forum.productcart.com/difference-response-addheader-vs-cachecontrol_topic5811_post21855.html#21855
