I have developed my website with asp.net and c# with MySql as back end. But even after optimizing css, Javascript and Images still takes time to load my website www.cloudionpro.com.
Please help do I need to change something in my coding or its a mysql server issue?
I loaded your site in Chrome and is reported the HTML of the page itself loaded in 93ms, of which 51ms was spent waiting for the HTML to be generated. 51ms is acceptable, but probably could be improved: it's likely you're making a lot of MySQL database calls that could be optimized (by paralleising them, or executing a query-batch).
Chrome reports the Google Maps API you're using failed to load, caused by scripting errors, which is also causing problems, open your browser's console for details of those. It looks like your site has a dependency on jQuery but your site never loads it.

I need to launch a web browser window from my .NET application that shows a web page that can be arrived to only by a POST request. I am definitely not allowed to do this with a temporary HTML file that contains a POST form. Any ideas how to solve this in another way? I have no idea what browsers are installed on users computers and I do not wish to have any requirements regarding this. Default browser would be the best.
Edit: Ok, as soon as I read my own question, I see one solution: to host e.g. a php script on my own server which would convert GET requests to POST requests and redirects to that web page. That php script can then be accessed with a simple link from my .NET application. Obviously, this involves an additional delay and complicates matters. Is there another solution?
No, there's no better solution other than the two you describe. https://textslashplain.com/2020/02/05/app-to-web-communication-launching-web-apps/ outlines the problem space.
I was wondering if anybody could direct me to any tools for debugging the cache.manifest file in offline HTML5 access. I recently downloaded a program called Manifesto which allows me to look up the cache manifest on loading a page. Everything seems to working fine however it keeps on saying that the status is "uncached". Obviously, it seems like although it is checking to make sure the cache files are there, it isn't actually caching them upon load. Whats going on and more importantly, how do I figure out how to solve it?
I got it to work. To be honest, it might have been working before but because I was having some different php scripts running in the background I had to be a little careful with pulling it up.
I have an HTML5/jquery mobile web app at http://app.bluedot.mobi. It is used for long distance races to track competitors via SPOT satellite tracking. The issue I have not yet resolved is that when loading the app when no data connection exists, the browser throws a "no data connection" alert popup as it is attempting to fetch the manifest during the checking event. Even when a data connection is present, loading the app can take a very long time. There are ~ 500 files to check. The fastest way to load the app (from a phone) is to be in airplane mode and dismiss the browser's alert - not so elegant.
Rather than force an update on users who tend to be in the backcountry with a spotty connection, I want to use applicationCache.update() programmatically, giving the user control over the process and speeding up app load whether on or offline.
Is this currently possible with the HTML5 spec and respective browser implementations?
Sounds like you need the abort() method. Unfortunately it is very new, and it will probably be a while before it is implemented by the majority of mobile browsers.
There are ~ 500 files to check.
It sounds like you're implying that the browser checks each file to see if there's any of them which has changed. This is not correct. The browser only checks the manifest file if that has changed, and that is a simple byte check. If the manifest file has not changed, the browser believes nothing has changed.
So if your application is slow to start, it might be your because your application is complex and there's alot of HTML and Javascript to parse. I would advise you to take a look at the application and see if there's anything you can optimize. In that case, you might want to take a look at Yahoo's Best Practices for Speeding Up Your Web Site page.
For example, I noticed you have a lot of Javascript code in the HEAD section. The beforementioned article advices us to move all Javascript (To the extent of what's possible) to the bottom of the page, so that the browser can start rendering the page as soon as possible. And there's a lot of other sound advice in the article. So take a look, I'm sure you'll find it useful. :-)
I am making a web app that is database driven and am having a hard time trying to figure out a way to cache article pages.
I've thought of just doing a cfquery to loop through all the article IDs to give me a page path (e.g. /?page=article&article_id=#id#) but from what I know of html5 caching is that if anything changes in the manifest file it will download everything all over again.
If updateready keeps getting triggered does it slow down the page significantly?
It shouldn't slow things down too much, because all that should be happening in the background, but it's not really the best approach. The app cache isn't intended for storing dynamic data, it's much better for static content. I would recommend caching a container page and then load the content into it with AJAX/JavaScript. Use local storage to keep your data for offline use on the client side.
This is an odd freeze. When I switch from source view to design view for an HTML or ASPX file, the client area freezes, but I can still click on other tabs and menus.
What am I missing here? Really don't feel like reinstalling VS2008.
I had the same problem, and found one resolution.
In VS 2008, In a page that was using a master page, the either frequency while working in source view or switching to design view, IDE would freeze for 10-20 seconds.
In my master template, I had references to the Google hosted JQuery, Jquery UI, and one or two more scripts off site. These were placed directly in my master page's head section.
I downloaded the js and then by deleting any offsite references, my IDE would be smooth again in both design and source mode.
I also discovered I could put the scripts inside my ToolkitScriptManager (I'm using AjaxControlToolkit) and added the Mode="Release", and could place the http://www.google.com references for the scripts. The IDE is still working fine for me.
This is often due to the Design mode downloading external resources that are timing out. As #JonK mentioned, for him it was jQuery references. I have seen this when the ConnectionString was set to production databases that could not be accessed on my development machine, even though I wasn't debugging (running) the site only editing code, it would still try to connect and because it couldn't it would stall waiting for the timeout.
VS2008 is mostly single-threaded for UI operations like this, so if it is downloading a slow or non-existent network path it hangs like this.
VS2008 can make all kinds of network requests, so these two examples may not solve it for you. The best way I have found to diagnose the problem is to use the Microsoft tool Process Monitor, filter by the Process webdev.exe, and watch for I/O requests that are long running and/or throwing errors. In my case, I could find the place that was having a problem because there would be a 20 second gap in between the hundreds of I/O entries in Process Monitor. Then, just back-tracked from when that gap began and I eventually found the request that was causing the problem.
This may not be possible for you, but if you can, an upgrade to VS2010 would help; it does a much better job of running process on multiple threads in more places so you don't have to worry about this as much.
Have you tried restarting your computer and then reopening your project?
