Package: python-webpy Version: 0.210-1 Severity: important What a horrible subject for a bug report! Hopefully I can make it make sense however.
Expected behaviour (lines beginning C: are sent from an http client to Apache; lines beginning S: are the response): C: POST / C: C: (postdata) S: 302 found S: Location: /ok C: GET /ok S: 200 OK S: S: Your POST was processed What actually happens: C: POST / C: C: (postdata) S: 200 OK S: S: Your POST was processed Now, my setup: Webpy 0.21, Apache version 2.2.3 with mod_scgi version 1.11. N.B., this only occurs with both Webpy 0.21 when accessed via SCGI. My first instinct was to file a bug against libapache2-mod-scgi, except that with Webpy 0.20 the bug goes away. Apache's config looks like this: SCGIMount / localhost:40232 I'm attaching scgitest.py which (if you run 'scgitest.py scgi 40232') will hopefully let you reproduce this bug. Here is a dump of the conversation between mod_scgi and the web application, which looks fine--you can see a request followed by a response, then another request and response: $ sudo ngrep -d lo port 40232 -x interface: lo (127.0.0.0/255.0.0.0) filter: (ip or ip6) and ( port 40232 ) #### T 127.0.0.1:44979 -> 127.0.0.1:40232 [AP] 39 36 38 3a 43 4f 4e 54 45 4e 54 5f 4c 45 4e 47 968:CONTENT_LENG 54 48 00 30 00 53 43 47 49 00 31 00 53 45 52 56 TH.0.SCGI.1.SERV 45 52 5f 53 4f 46 54 57 41 52 45 00 41 70 61 63 ER_SOFTWARE.Apac 68 65 2f 32 2e 32 00 53 45 52 56 45 52 5f 50 52 he/2.2.SERVER_PR 4f 54 4f 43 4f 4c 00 48 54 54 50 2f 31 2e 31 00 OTOCOL.HTTP/1.1. 53 45 52 56 45 52 5f 4e 41 4d 45 00 XXXXXXXXXXX SERVER_NAME.XXXX XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXXXXXXXXXXXXX 00 53 45 52 56 45 52 XXXXXXXXX.SERVER 5f 41 44 4d 49 4e 00 5b 6e 6f 20 61 64 64 72 65 _ADMIN.[no addre 73 73 20 67 69 76 65 6e 5d 00 53 45 52 56 45 52 ss given].SERVER 5f 41 44 44 52 00 XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX _ADDR.XXXXXXXXXX XXXXXXXXXXX 00 53 45 52 56 45 52 5f 50 4f 52 54 XXXX.SERVER_PORT 00 38 30 00 52 45 4d 4f 54 45 5f 41 44 44 52 00 .80.REMOTE_ADDR.
