Hi all,

When I do TFPHTTPClient.HTTPMethod() to connect a server which is
actually not available, it will wait for a longtime to return.

I searched the forum and found that TFPHTTPClient has a property named
ConnectTimeOut. But when I wrote some code like:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i var 
HTTPClient: TFPHTTPClient;begin  HTTPClient :=
TFPHTTPClient.Create(nil);  ...  HTTPClient.ConnectTimeOut:=1000;end; 
It can not be compiled and I got a hint ：Error: identifier idents no
member "ConnectTimeOut"

I Checked the file fphttpclient.pp and did not see anything like
"ConnectTimeOut"

I wonder if TFPHTTPClient really has a parameter named ConnectTimeOut?
How can I wait shorter if the server is not available?

ps: I also set IOTimeout property to 1000, but it seems not work. It
waited around 10 seconds to return when the server is not available.

the idea of ConnectTimeout came from:

From which date is your Free Pascal version ?

I am using FPC3.0.4 installed together with Lazarus 2.0.6.

After reading your reply, I downloaded fpc-3.0.4.source.zip from
sourceforge, there is still no ConnectTimeout in fphttpclient.pp.  But
FPC3.0.4 should be the newest version according to
https://www.freepascal.org/download.html

Then, I downloaded the newest fphttpclient.pp (modified 2 monthes ago)
from github and replaced the old file. There is ConnectTimeout inside
and Lazarus IDE can recognize it and put it in the to-choose box when
I typed "HTTPClient."

But I still got a Error: identifier idents no member "ConnectTimeOut"
when I tried to compile it.

I guess it because fphttpclient.ppu is still the oldversion. but I
don't know how to compile it.

What should I do?

My bad senglit, so apologies.

I thought the 3.2 release candidate was a well-known fact:

To bump the thread so TS is aware:

@senglit: Also take note of this thread:
https://forum.lazarus.freepascal.org/index.php/topic,49356.0.html

I am not sure how/what to advise, in your circumstances. I use
Freepascal and Lazarus from trunk and, I have no idea if Lazarus 2.0.8
will work without any issues in combination with Freepascal 3.2rc1
