Question

I am using TIdHTTPProxyServer and now I want to terminate connection when it is success to connect to the target HTTP server but receive no response for a long time(i.g. 3 mins)
Currently I find no related property or event about it. And even if the client terminate the connection before the proxy server receive the response from the HTTP server. OnException Event will not be fired until the proxy server receive the response. (That is, if the proxy server still receive no response from HTTP Server, I even do not know the client has already terminate the connection…)

Any help will be appreciated.

Thanks!

Indy uses infinite timeouts by default. To do what you are asking for, you need to set the ReadTimeout property of the outbound connection to the target server. You can access that connection via the TIdHTTPProxyServerContext.OutboundClient property. Use the OnHTTPBeforeCommand event, which is triggered just before the OutboundClient connects to the target server, eg:

#include "IdTCPClient.hpp"

void __fastcall TForm1::IdHTTPProxyServer1HTTPBeforeCommand(TIdHTTPProxyServerContext *AContext)
{
    static_cast<TIdTCPClient*>(AContext->OutboundClient)->ReadTimeout = ...;
}
