Dear Support,

While evaluating dynamsoft we are facing the following issues request your help asap on it to complete our evaluation.

We tried a standalone example of dynamsoft scan and upload images to pdf format with form based authentication with custom authorization.
Our observation is that a new session id is generated on HTTPUploadThroughPostAsMultiPagePDF() and the prior session is lost. Request your guidance on the same. We're using IE9+ version.

Thanks and Regards

Dear Cecila,

Dynamic Web TWAIN acts a s a separate agent when uploading, this is why session gets lost. The working solution now is to use JavaScript's AJAX upload instead of the built-in upload methods of Dynamic Web TWAIN. The steps are:

1. Convert image(s) to a base64 string
2. Upload the string to the server
3. The action page decodes and saves the image(s) on the server.

Please check http://kb.dynamsoft.com/questions/841/H ... +with+AJAX

Please let me know if I can be of any further assistance.
