TFPHTTPClient what is the default timeout when doing a get?

There is the IOtimeout option should I use it or just let it handle it
the default way?

Here is some info I found

Internet Explorer imposes a time-out limit for the server to return
data. By default, the time-out limit is as follows:

Internet Explorer 4.0 and Internet Explorer 4.01   5 minutes
Internet Explorer 5.x and Internet Explorer 6.x   60 minutes
Internet Explorer 7 and Internet Explorer 8   60 minutes
When the server is experiencing a problem, Internet Explorer does not
wait endlessly for the server to return data.

>>"Applications that use the WinINet API directly will experience the
following ReceiveTimeout values:"

WinINet.dll version 4.x   5 minutes
WinINet.dll versions 5.x and 6.x   60 minutes
>>"WinINet.dll versions 7.x and 8.x   30 seconds" (So I am assuming
pascal uses the wininet.dll in windows?)

You can locate the version of WinINet.dll in the %windir%\system32
directory.

The problem is I need more than a 30 second wait time on the site I am
getting the info from, because it is very busy at times. I increase
it, but it seems to always fail around the 30 second mark as indicated
above.

Says infinite timeout on most platforms, does that include windows?

Yes, or at least it should since it's a requirement for BSD sockets
compatibility, which Winsock adheres to.
