Hi,
today debugging my app with Http module (9.4.1 .net 32 bit) I discovered strange problem with some urls, when I invoke
_http.SynchronousRequest(_uri.Host, _uri.Port, _uri.Scheme == Uri.UriSchemeHttps, _req);
it's doing 4 times the same POST request and response is null and I don't know why. On other urls everything works good. GET requests is working fine.
I only discover "Actual content-length not equal to calculated content-length" in LastError

This new build should fix the problem:
http://www.chilkatsoft.com/preRelease/ChilkatDotNet4.zip
Internally, SynchronousRequest and other HTTP methods might respond to HTTP responses by sending a subsequent request as indicated by the response. For example, if the HTTP response is a redirect, or if it's a response that indicates authorization is required, such as w/ NTLM.
It's impossible to know what happened because you did not post the HTTP responses. You need to clearly post the sequence of requests and responses. (If there is bulk data within a request or response, that can and should be omitted.)
Also, the LastErrorText you posted is useless because you did not maintain the line-endings. Posting a long LastErrorText as a single line of text is not helpful.
I have updated LastErrorText to multilines (previous there was rn) In error text the error is "Actual content-length not equal to calculated content-length" and Chilkat library doing the same request many times
In previous post I don't HTTP Response because there is no response - HttpResponse is null. After POST Request is another POST Request and another - with no responses for them
Also I posted direclty when the bug exists - when using _req.ContentType = "multipart/form-data" (image upload) and non english characters in request params (for examples russian chars), directly when I post:
RequestItem:
name: joinSubmit
value: ادامه
wihtout joinSubmit or when it's value is "aaaa" everything works fine (or when I don't upload image ther is also ok)
I hope now all is good explained
