I'm trying to intercept file upload requests using the mod_ext_filter module in input mode. I've tried a few test commands to write the STDIN to a file, for example: /usr/bin/tee /tmp/ext_filter_debug And also tried a test script that does basically the same thing: #!/bin/sh cat - > /tmp/ext_filter_debug If I send a large file I can see the request append /tmp/ext_filter_debug file, but as soon as the request completes, the file goes down to 0 bytes in both instances. I don't understand how this is even possible given that the module should have no idea what file I'm writing to. Interestingly if I try this: #!/bin/sh cat - > /tmp/ext_filter_debug cat /tmp/ext_filter_debug The /tmp/ext_filter_debug file hangs out a while longer, duration depending on size, but then eventually goes to zero. Eventually, I want to parse the request and encrypt the uploading file using openssl smime, but I don't understand how to work with the incoming request. The only error I see logged is: (9) Bad file descriptor: apr_file_close(child input)To /var/log/apach2/error.log. I tried LogLevel=debug and DebugLevel=9. LogStderr helps to see if I have a problem in the cmd script itself, but otherwise isn't much help. Can any provide any examples for this use case? Thank you, Jon Belanger
