too slow in using Net::HTTP.post_form

[Ak 756]

Hi

I am using Net::HTTP.post_form to post cgi request to a website and get
answers.
Below is my code and I found that it always take about 30s to return the
result. I think my Internt connection is not so slow as I paste the same
cgi request url and run in my firefox, it will get result in less then
10 second.

puts Time.now
post_result= Net::HTTP.post_form(URI.parse(url),params)
puts Time.now

So, how can I make the post_form returns quickly?
And, I also found many tags like <img src=xxx.gif> in the returned html
file. Did the post_form download all those gif files? If so, how can I
discard all the image file and only get the text result?

Thanks in advance.

You might post more of the code.

Maybe the particular server you are testing reacts differently if you
don't have a session, a referer or the right user-agent ?

And, I also found many tags like <img src=xxx.gif> in the returned html

No, it didn't.

Hi

Below is my code:
----------------------------------------------------------
require 'net/http'

params = {'s'=>'GOOG'}
url='http://finance.yahoo.com/q'
puts Time.now
post_result= Net::HTTP.post_form(URI.parse(url),params)
puts Time.now
----------------------------------------------------------

And its running result:
Wed Aug 15 09:11:48 +0800 2007
Wed Aug 15 09:12:02 +0800 2007

I think this is slow since the post_form will not downloading pictures
in the post reply page. And when I type the url
'http://finance.yahoo.com/q?s=GOOG' in my firefox , it will show the
complete page including pictures in about 10s. If I configure the
firefox to not download pictures, it need only 4s. So,how I can I make
post_form reply more fast?

The same code takes less than a second for me. Perhaps it is your connection?
