MemoryStream Multiplexer - Write and Read from many threads (omaralzabir.com)

submitted by oazabir(1805) 1 month, 23 days ago

Here’s an implementation of MemoryStream like buffer manager where one thread can write and many threads can read simultaneously. Each reading thread gets its own reader and can read from the shared stream on its own without blocking write operation or other parallel read operations. It supports blocking Read call so that reader threads can call Read(…) and wait until some data is available, exactly the same way you would expect a Stream to behave. read more...

Cache WCF Javascript Proxy on Browser(omaralzabir.com)

submitted by oazabir(1805) 1 month, 23 days ago

When you use WCF services from Javascript, you have to generate the Javascript proxies by hitting the Service.svc/js. If you have five WCF services, then it means five javascripts to download. As browsers download javascripts synchronously, one after another, it adds latency to page load and slows down page rendering performance. Moreover, the same WCF service proxy is downloaded from every page, because the generated javascript file is not cached on browser. Here is a solution that will ensure the generated Javascript proxies are cached on browser and when there is a hit on the service, it will respond with HTTP 304 if the Service.svc file has not changed. read more...

Prevent ASP.NET cookies from being sent on every css, js, img request(omaralzabir.com)

submitted by oazabir(1805) 7 months, 12 days ago

Automatic JS, CSS versioning to force update browser cache(omaralzabir.com)

submitted by oazabir(1805) 11 months, 28 days ago

When you update javascript or css files that are already cached in users’ browsers, most likely many users won’t get that for some time because of the caching at the browser or intermediate proxy(s). You need some way to force browser and proxy(s) to download latest files. Here's an HttpFilter that will automatically generate new URL for changed files. read more...

Safely deploying changes to production server(omaralzabir.com)

submitted by oazabir(1805) 1 year, 3 months ago

When you deploy incremental changes on a production server, which is running and live all the time, you some times see error messages like “Compiler Error Message: The Type ‘XXX’ exists in both…”. Sometimes you find Application_Start event not firing although you shipped a new class, dll or web.config. Sometimes you find static variables not getting initialized and so on. There are so many weird things happen on webservers when you incrementally deploy changes to the server and the server has been up and running for several weeks.

Quick ways to boost performance and scalability of ASP.NET, WCF and De(omaralzabir.com)

submitted by oazabir(1805) 1 year, 5 months ago

By tweaking system.net changes, you can increase the number of parallel calls that can be made from the services hosted on your servers as well as on desktop computers and thus increase scalability. By changing WCF throttling config you can increase number of simultaneous calls WCF can accept and thus make most use of your hardware power. By changing ASP.NET process model, you can increase number of concurrent requests that can be served by your website. And finally by turning on IIS caching and dynamic compression, you can dramatically increase the page download speed on browsers and and overall responsiveness of your applications. read more...
