Is there any free web based cron that can do scheduled jobs ....
http://www.mywebcron.com/
but why would you want a web based cron over a standard crontab?
You can do (for free, unless your load's very heavy) periodic cron-like "sending of mails" with Google's App Engine, with Java or Python -- but I don't know of a free service that will let you do that with asp.net (or other .NET code).
Here's an couple of old articles on how to implement a cron job with ASP.NET: Simulate a Windows Service using ASP.NET to run scheduled jobs and Scheduled ASP.NET Task (ASP.NET Cron Jobs).
You basically just add something to the cache, and when the item expire you can use that event to trigger your code. Simple.
You can also try www.thecloudblocks.com which includes a web UI and RESTful API

I have a project in which I have implemented hundreds of scrapy spiders.
Now I collided with the following problems:
time to time websites changes their DOM/API - so spider stop working or not all info collected
websites became unavailable or moved to another domain - spider stop working.
Since there are a lot of spiders it not easy to monitor the status of each spider.
is there any framework that provides the ability to monitor scrapy spiders?
status of running spider(s)
show when spider(s) stop working etc.
I have looked into scrapinghub/zyte but not sure if it good for our purpose because we need something that can be running locally.
Scrapydweb is basically just like Scrapinghub but you run it locally.
It can alert you when spiders fail with email/slack if I remember correct. It's a bit less user-friendly than scrapinghub since you have to manage servers and so on. But overall I think it was a good platform when I used it.
Airflow is a very handy platform for scheduling and monitoring.

I have an ASP.NET application which is configured to run on my local IIS.
Anyone knows any Free Record/Replay Web Testing Tool so that I can test the pages with e.g. 10 concurrent users?
(I don't have access to Visual Studio Test/Ultimate edition to use its Web Testing tools.)
Thanks
You may checkout the soapUI/loadUI suite.
check Selenium tool http://seleniumhq.org/
and seleniumgrid http://seleniumgrid.thoughtworks.com/
Selenium Grid allows you to run Selenium tests in parallel, cutting
down the time required for running acceptance tests to a fraction of
the total time it currently takes.

I am looking for a third-party service or tool that can trigger or hit a web page at scheduled times. Does anyone know of any? I currently use my windows scheduler to hit these pages, but there are gaps in this since I don't run my computer 24 / 7.
There are lots of free website monitoring services out there that check your site's availability by testing whether a given URL responds properly. One that I use is http://mon.itor.us/ Give it the URL of your page and that will do the trick.
One other alternative is Pingdom. They offer a free account for monitoring one web site. You can set Pingdom to send email or SMS if your site goes down and you can configure the service to hit your page for example once in every 5 minutes. You can set the check resolution quite freely.
Some other alternatives are MonitorUs (which RichieHindle already mentioned), SiteUptime and HyperSpin.
I created an open source app called Pinger. You can do unlimited URLs with intervals of your choosing. The docs has instructions for getting running on Heroku quickly:
https://github.com/austinthecoder/pinger
Only problem is, currently, you can only set an interval, not a specific time.

Hai guys,
Is there any alternative for windows scheduler for an asp.net application... The alernative must be capable of doing scheduled tasks as i am into shared hosting where i cant add any task scheduler to my server... I know there is quartz.net but my application needs only one task to be scheduled daily so i dont want to use it.... Any other alternative which can carry out scheduled tasks for me....
One way to do this is..
You can write a windows service which will call your application url over a given period of time recurrently. Install and run this service from your personal computer or any other computer that you is mostly [almost 24x7] online.
Another way to this is..
use website uptime checking services. They call your URL at an interval. There are many free and paid services. I found this one to be good enough after some googling.
http://host-tracker.com/order-page/
Instead of a Windows Service you could always just write a simple powershell script to execute at certain intervals, 3 lines of code.
$ie = new-object -com "InternetExplorer.Application"
$ie.navigate("http://www.stackoverflow.com")
$ie.visible = $true

A good detailed tutorial on the lifecycle of a page request.
I've read up on the ASP.NET page lifecycle, I am talking about things that happened before the .NET process starts to handle the request.
i.e. domain typed into browser, DNS mapping? etc.
For Quick Reference:
I use the following chart all the time, it is hanging by my desk:
http://blog.krisvandermast.com/ASPNET20PageLifeCycle.aspx
As well as a detailed version of each stage:
http://john-sheehan.com/blog/wp-content/uploads/aspnet-life-cycles-events.pdf
I found this MSDN article really interesting, hope you like it too.
I would read ASP.NET Application Life Cycle Overview for IIS 5.0 and 6.0:
Within ASP.NET, several processing
steps must occur for an ASP.NET
application to be initialized and
process requests. Additionally,
ASP.NET is only one piece of the Web
server architecture that services
requests made by browsers. It is
important for you to understand the
application life cycle so that you can
write code at the appropriate life
cycle stage for the effect you intend.
