You should be using asp.net and there are plenty of support sites like aspdotnetatoms.com that offer free snipplets of code and tutorials.

Hi, sorry I have not seen your replay.
Why you think that it broken?
1) Imagine you have AJAX form with link that you would like to use like a button that does not redirect, but simly changes state of the form (e.g. Open/Show Details, Navigate through wizard steps, etc). This is case when you can use postback links. They are very useful in this scenario. Okay, I am sure that you can use simple link to do this, But what is the point to do more work?
2) Get im mind MVC/MVP pattern, if you would like to encapsulate navigation logic. How you perform this without postback? Sure, you can generate script, but if logic is very complex you will need to make AJAX call to the server… This also will add unneeded complexity.
3)…, I can prove additional comments, but in real life you simply need to start play with asp.

Mike: it’s not my website I’m trying to manipulate. Therefore, I can’t control the type of links they choose. Moreover, if there’s two types of link, a good one and a broken one, why in hell would you offer both types? Just offer the non-broken one and be done with it.

Hehe. I do not know if there word “lamer” in the englesh. However sil is “lamer”. If you will spend some more time on asp.net you will be able to see that there two types of the links. One of them is normal links and second that works with back end(javascript links). You may choose from link you like and use it. Also if you do not know in if you need something invoke on the server you can use webservices, in asp.net this is very easy, just create aspx file and place needed method in it.

@Merlin: thanks! I’ve trying to discover what happened that I couldn’t fetch an .aspx page with form data. It is nasty.

Ross: it doesn’t. The links are javascript: links, not real links. :(

Turn off Javascrpt in your browser and see what it does instead - because it should work without JS. The ViewState is most likely base-64 encoded and used in some cases to replace the use of Session (and obviously to remember the state of the controls on the page)*. You can run an app without viewstate, though.

* Apparently 2005 lets you store the Viewstate in the session.

Funny you should say this…

We have a very very slow - very very boring Timesheet system at work that $BOSS is very very insistant I keep filling in.

I wrote a Python command line interface to it using cookielib and urllib2

And yep.. I had to pass a huge __VIEWSTATE variable back to the server.

The command line interface rocks though - I can fill in 5 entries in about the same time it took the ASP page to reload after changing categories.

yup, you have to send a field in your post that has the whole freakin’ viewstate in it.

I wrote a tool that will let you do this from the command line if you set it up to do so.. there is a sample explaining ASP.NET viewstates here:

What I usually do in such situations is to sniff what is actually sent by a browser. The quickest way is to run a netcat nc -l -p 1234 and before posting the request, change the proxy to localhost:1234. That’ll simply print the query on your console.

The other option is to use a HTTP::Proxy perl module to sniff everything going through it. I can send you my “sniffer” if you like.

Anyway, I do agree that it sucks.
