Getting Indy Error "Could not bind socket. Address and port are already in use"
- by M Schenkel
I have developed a Delphi web server application (TWebModule). It runs as a ISAPI DLL on Apache under Windows. The application in turn makes frequent https calls to other web sites using the Indy TIdHTTP component. Periodically I get this error when using the TIdHTTP.get method:
Could not bind socket. Address and port are already in use
Here is the code:
IdSSLIOHandlerSocket1 := TIdSSLIOHandlerSocketOpenSSL.create(nil);
IdHTTP := TIdHTTP.create(nil);
idhttp.handleredirects := True;
idhttp.OnRedirect := DoRedirect;
with IdSSLIOHandlerSocket1 do begin
SSLOptions.Method := sslvSSLv3;
SSLOptions.Mode := sslmUnassigned;
SSLOptions.VerifyMode := [];
SSLOptions.VerifyDepth := 2;
end;
with IdHTTP do begin
IOHandler := IdSSLIOHandlerSocket1;
ProxyParams.BasicAuthentication := False;
Request.UserAgent := 'Test Google Analytics Interface';
Request.ContentType := 'text/html';
request.connection := 'keep-alive';
Request.Accept := 'text/html, */*';
end;
try
idhttp.get('http://www.mysite.com......');
except
.......
end;
IdHTTP.free;
IdSSLIOHandlerSocket1.free;
I have read about the reusesocket method, which can be set on both the TIdHttp and TIdSSLLIOHandlerSocketOpenSSL objects. Will setting this to rsTrue solve my problems? I ask because I have not been able to replicate this error, it just happens periodically.
Other considerations:
I know multiple instances of TWebModule are being spawned.
Would wrapping all calls to TIdHttp.get within a TCriticalSection solve the problem?
