Subject Re: [users@httpd] Handling multipart/form-data requests via Apache Module
Date Thu, 21 Jan 2010 19:02:03 GMT
Hello Devraj,

Thanks for the quick response.

I am using C to write my module.

Can you give me some guideline to decode the mime string? If the contents
of multipart data is just text file, it is easy to read it and write to
other file, but in case of zipped file or image file, how this is to be
handled?

Language is not a problem, If there is better way to do this in Perl or
Python, I can do that also.

Regards,
- Sachin Jain
