I am using wget for Windows (gnuwin32 wget-1.11.4-1) in Windows 8 and using it for a helpdesk tool called Kayako, telling it to poll from an email queue. The command line looks like this:
wget.exe -O null --timeout 25 http://xxx.kayako.com/cron/index.php?/Parser/ParserMinute/POP3IMAP
I know it takes around 20 seconds to receive a response from the server in my particular case when using a browser with the URL in the command line above. However, when using that command, it returns almost immediately. This is an excerpt of the output:
Connecting to xxx.kayako.com[xxx.xxx.xxx.xxx]:80... connected. HTTP
request sent, awaiting response... 200 OK Length: unspecified
[text/html]
I would like to know what would be the difference between the two cases and how could I get wget to behave in the same way as the browser (I know it doesn't because Kayako is not polling from the email queue).
Answer
Some websites offer browser optimized pages. That means the site checks on a request what kind of browser you are using and serves you with an optimized page or as a fallback a standard page.
Also java-script could be a problem see link
