The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

__DoPostBack Problem: Get all friend pages on MySpace - Urgent!!!

Tags: myspace
This question is related to two old questions:
http://www.experts-exchange.com/Web/Web_Languages/JavaScript/Q_22102639.html
http://www.experts-exchange.com/Programming/Languages/Scripting/JavaScript/Q_22115113.html

It seems MySpace changed their page navigation method again. I'll restate my question here. Basically what I'm trying to do is to get all the friendIDs of a MySpace user using PERL. After "click View all friends" on a user's profile, we can see the first page of friend list. What gave me trouble was MySpace uses __dopostback javascript for navigating through Page 1 to Page2 (Suppose this user has 58 friends.) I read the solutions to the above old questions and used the following to specify the right page numbers and submit the form. (Here since I know the second form is the right form, I used @form[1] directly.)
      @forms[1]->push_input('hidden', {name => '__EVENTTARGET', value => 'ctl00$cpMain$FriendsView$pagerTop'});
      @forms[1]->push_input('hidden', {name => '__EVENTARGUMENT', value => $PageNum});
      @forms[1]->push_input('hidden', {name => '__VIEWSTATE', value => $ViewState}); # Variable $ViewState is obtained using RegEx matching.
      @forms[1]->make_request;
However the resulting page says "Object moved".
 
Could you help me out on this? Thanks a lot.

> However the resulting page says "Object moved".

That means that the page is doing a redirect. The http header contains a value with the key "Location". Read that value to find out where the page is redirecting to.

Thanks, however, I cannot find the key "Location" in the http header.
The whole page only contains the following:

<html><head><title>Object moved</title></head><body>
<h2>Object moved to <a href="/Error.aspx?ETH=51c17639ab0bc882dd5242113350586f&amp;EOH=08239f21b499ca10fee00fe7c4ff2f2b">here</a>.</h2>
</body></html>

That's because you are not looking in the http header. That's the contents of the response, not the header.

However, you can also find the url in the href of the link in the content. It seems as there is something wrong with what you are sending to the page, so that you get an error message. Follow the link in the page to see what error message you get.
