On PageSpeed Insights they recommend highly doing two things:
1) Leverage browser caching
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
2) Enable compression
Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.
We are with Network solutions and believe they are using IIS 6 with regular asp.net code. Some of the images are using Amazon S3/Cloudfront.
How do we implement the above items? I see a lot for IIS 7.
I'm using output caching in my custom HTTP handler in the following way:
public void ProcessRequest(HttpContext context)
{
TimeSpan freshness = new TimeSpan(0, 0, 0, 60);
context.Response.Cache.SetExpires(DateTime.Now.Add(freshness));
context.Response.Cache.SetMaxAge(freshness);
context.Response.Cache.SetCacheability(HttpCacheability.Public);
context.Response.Cache.SetValidUntilExpires(true);
...
}
It works, but the problem is that refreshing the page with F5 leads to page regeneration (instead of cache usage) despite of the last codeline:
context.Response.Cache.SetValidUntilExpires(true);
UPD: Seems like the cause of problem is that HTTP handler response isn't caching on server. The following code works well for web-form, but not for handler:
Response.Cache.SetCacheability(HttpCacheability.Server);
Are there some specifics of the caching the http handler response on server?
I've a Gridview control using an ODS(ObjectDataSource) to fetch data. For the best performance and efficiency, I've turned-off the view state of Gridview (i.e. EnableViewstate = "false".And I've also enabled caching in the associated Objectdatasource. This eliminates as much as 50-60% performance optimization because it eliminates the DB round-trip .. courtesy ODS Caching.So, after this I got stuck into the famous "ODS sorting" issue but I managed to invent a tricky solution for it and its working fine
View 4 RepliesI am trying to use output caching on my .net pages but it is not working when I use Route handlers to redirect request to actual page, but it works when I call the page directly.
also one more weird thing is that when I am debugging and using .net instance of IIS http://localhost:64293/test it is working, but when I deploy it and try to call the page it is not caching i.e. http://www.mydomain/test(but it works if I call the page directly)

i have a custom handler which captures user's book mark entry. To debug this handler, i have created a file "test1.txt" in code behind which saves the user entry. After the debug, i removed the text file (test1.txt) then re-complied the web app and deployed new DLLs for the site. But, the site is still looking for test1.txt file. i dont know how to confirm if the handler is really removed from the new DLL. Also, looked at the handler code behind file and didn't find any entry with test1.txt. So,
View 1 RepliesI have a admin page in asp.net that adds data to a database. This database is available as a JSON string to external websites, however, since it's a lot of data, the external websites cache this data locally.I want to be able to ping the external websites to let them know the data has changed so they can referesh their cache. I figure I can setup an ASHX handler that receives a parameter telling them what data has changed, so they can both delete that data and refresh it.The only part I'm not sure about is the best way to call this external page from my admin page. Do I just do a regular WebRequest and discard the result? or is there a simpler way to call a page from code when you don't need the response?

I am a bit confused about these two sequence of events or processes happening in conjunction to each other. Does the page handler executes first or does the somepage.aspx get execute first or do they happen simultaneously?

In our web application we need to keep various company's settings. For eg "DiamondProdRefIDCaption","Shippingpickup","ZipCodeCaption","DefaultCountry","AllowToEditInvoice", etcThese settings are different for various companies and are placed in web.config as key-value pair.Initially, we have tried do simplify this process by adding a company_settings table in the DB so as to allow us to add companies on the fly. However, this method makes it very difficult to add a new setting

View 2 RepliesI've spent a while trying to figure this one out, . I am trying to implement a simple jax.actionlink(first time using) on rows in a table to remove the record from the user control. The ActionLink httpMethod is set to POST but it is not even hitting the Post action I have in the controller. It just gives me a 404 Resource not found error everytime.
I checked fiddler and the reason why I think is because its doing a GET instead of the value i set of POST. I dont have a get method for this since its just an ajax call to delete a record and return a partial view back to the div. I put a breakpoint in the POST method and definitely is not hitting that method. I'm not sure if its something simple or a configuration/routing issue or IIS issue. I've tried in chrome and IE8 just in case.

I used following to cache my ASP.NET page.
Response.Cache.SetExpires(DateTime.Now.AddSeconds(60));
The problem is when I send AJAX (XmlHttpRequest) request from other page to this page, that response does not get cached on any browser but IE. (On IE, it gets cached even if I don't specify). How do I make it cache?
I create custom HTTP handler for auto generating file and I want to tell IIS7 to serve current request like normal static file because I need to use IIS and web.config file to control compression setting and any other HTTP header of current requested file.I know. there is an internal class called StaticFileHandler in ASP.net. But I cannot access it. Or you have any other way to work like this.
