Hallo,
I'm currently realizing a web server for my company which allows control of some of our embedded devices. After some research, I decided on python and twisted as the way to go using genshi as templating engine, which works very well. The problem I encountered is as follows: The user of the web panel should also be able to upgrade the firmware on our device. To make this possible, a file upload has to take place. The firmware file can have a size of up to 150MB, so it will not fit in the RAM of our device. It either won't fit on the NAND flash chip twice, so it should be written to NAND with its final name and not as a temporary file. To tell the server where to store the file upload, I could add a hidden input to the upload form indicating the type of the file being uploaded, so that the web server can save it to the right location. Where's the place to hook in twisted to implement such a behaviour? Do I really have to write a completely independent implementation of the HTTP handler or could I also reuse some parts of twisted.web? Does some code exist already which implements the wanted behaviour or could be modified to implement it?
You can override `Request.gotLength` to inspect the request and select an appropriate destination for the request body. You can convince Site to use your custom request by setting it as the `requestFactory` attribute. Jean-Paul
