Hi,
I'm using an application called " aspeasypdf " for creating PDF files on the fly and mail it to the the customers. This setup was working fine in IIS 6.0. We are current in the process of migrating this domain to a new server with Windows 2008 R2 and IIS 7.5. Here the application fails to create throwing the error:
HTTP Error 404.0 - Not Found
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.
Requested URL http://locahhost:80/PDFfiles/25752.pdf
Physical Path C:\locahhost\PDFfiles\25752.pdf
Logon Method Anonymous
Logon User Anonymous
I understand that this error means the PDF file is not in the directory. But as per code this file should be created automatically. This same setup is working without any issues in the IIS 6.0 server.
I have tried assigning modify permission for the following " everyone, users, IIS_IUSRS, ANONYMOUS login, IIS AppPool\asp.net 2.0 application pool "
I'm new to this.. so please bare with me.. :)
Some forum suggested that i need to add ISAPI extension for PDF. But i don't know how. Further, some suggested that i need to add exception in web.config i don't know how to do that too..
