    <p>I'm having a persistent problem using Indy 10 where I am posting a string of XML encoded as a <code>TIdMultiPartFormDataStream</code>, the code that I am using to invoke the POST is given below. A majority of the time, this works no problem, however I am getting a repeated error when running on Windows 7 that throws a #10060 Connection Timeout socket error only when the XML string is longer than 32767 bytes, anything under that size works without a problem.</p> <p>I have verified that it is not related to the server I am posting to, as there is no problem for messages of any size sent with the same code/application on Windows XP. </p> <pre><code>IdHTTP2 := TIdHTTP.Create(); UsingHTTPS := (Pos(LowerCase('https://'), Trim(LowerCase(URL)))&gt; 0); if UsingHTTPS then begin IdSSLIOHandlerSocketOpenSSL2:=TIdSSLIOHandlerSocketOpenSSL.Create(); with IdSSLIOHandlerSocketOpenSSL2 do begin SSLOptions.Method := sslvTLSv1; SSLOptions.Mode := sslmUnassigned; SSLOptions.VerifyMode := []; SSLOptions.VerifyDepth := 0; Port := 443; end; end; //if UsingHTTPS try try with IdHTTP2 do begin //with some browser style defaults AllowCookies := False; ProxyParams.BasicAuthentication := False; //ProxyParams.ProxyPort := 0; Request.ContentLength := data.Size; Request.host := ''; Request.CustomHeaders.Clear; Request.Accept := ''; Request.ContentEncoding := ''; IOHandler:=IdSSLIOHandlerSocketOpenSSL2; ReadTimeout := -1; end; //http post IdHTTP2.Post(URL, data, response); </code></pre> <p>Does anyone have any recommendations to solve this problem? I tried to set the <code>ReadTimeout</code> variable but this had no change. Any pointers to solve this problem would be much appreciated. </p>

    1. COIs there a difference in the MTU size between the two clients? If the code works on XP but not on 7 maybe there's some environmental issue.

    2. COI generally don't set the content length and let the component calculate the size. Also, consider enabling `sslvrfPeer` mode in the SSL `VerifyMode` options, otherwise the server certificate isn't validated, and you're wide open to man-in-the-middle attacks.

    3. COUse a packet sniffer, such as Wireshark, to make sure data is actually being transmitted back and forth in a timely manner. Or at least look at the call stack when the exception is raised to see if the timeout is occurring during the SSL handshake, while sending the request, or while receiving the response.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
