Hi,

I've spent quite a bit of time trying to get this to work, but so far to no avail.

I'm attempting to request information from a specific .aspx page.

Using firefox and firebug, I am able to determine the actual url and parameters and if I paste into one of several browsers, the result I am looking is returned satisfactorily:

http://widgets.ghin.com/HandicapLookupResults.aspx?entry=1&dynamic=&small=0&css=default&ghinno=9675575&hidename=0&showmsg=0&showheader=1&showtabheader=0&combinehieff=0&showheadertext=0&showfootertext=0&tab=2

I found I can even shorten this (I assume the other parameters are defaulted) and it works just as well:

http://widgets.ghin.com/HandicapLookupResults.aspx?ghinno=9675575

Now I have read something about the requirement to use VIEWSTATE, which I as understand would be the state from the previous form.  However, as you can see by using the above url's it seems to work fine without going through the form.  However, if it helps anyone understand this better this would be the url to the form:

http://ghin.com/lookup.aspx

and my inserting the number 9675575 in the field you can achieve the same results as above.

I have tried coding this up in a variety if ways without success.  see attached.

I would appreciate any help plus how the solution was thought out.

Thanks

If the url doesn't require a post and the page can be retrieved correctly by calling up the full url with parameters, I would think that would be the best way to do it rather than doing a CURL post

Perhaps, but I need to be able to scrape the page and using curl will allow me to have the result returned to a variable, where I may process the contents.
