Category: win32 Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: cheeng shu chin (cheengshuchin) Assigned to: Nobody/Anonymous (nobody) Summary: isapi extension seem Error for large file posting in iis Initial Comment: hi all, I try to submit a large file (2Mb+) to iis with pywin32 isapi extension via html form (POST method), but end out with "The page cannot be displayed" for IE and "server connection reset" for firefox. This happen even with attached module "C:\Python24 \Lib\site-packages\isapi\test\extension_simple.py". The form with this "CONTENT_TYPE=multipart/form-data; boundary=---------------------------7d629bf20426" is it a limitation in isapi or some bug in it??? can someone help me on this??? ---------------------------------------------------------------------- >Comment By: cheeng shu chin (cheengshuchin) Date: 2006-10-24 04:40 Message: Logged In: YES user_id=1546069 i had check with 'live headers' seem no error. is it a memory leak issue in here??? as i still can post a large file(python-2.4.4.msi) to the page(>2MB). I still have result from win32traceutil window output but seem "truncated".... and browser reply with "The page cannot be displayed" please refer to attachment.....:) ---------------------------------------------------------------------- Comment By: cheeng shu chin (cheengshuchin) Date: 2006-10-24 04:28 Message: Logged In: YES user_id=1546069 if I post a smaller file (<1MB), the semple seem work fine, but will fail on large file.... i found it('live headers') already, as priviously i try to find it via FF extension search only...:( those sample(extension_simple.py & advanced.py) only work with small file submit but not for bigggg file....

Let's just take this to email, but unless the samples work, your POST example isn't going to. I typed "live headers" into google and the first hit was the correct link from mozdev.org, as were most of the top 10 - I'm surprised you had trouble finding it. ---------------------------------------------------------------------- Comment By: cheeng shu chin (cheengshuchin) Date: 2006-10-23 11:07 Message: Logged In: YES user_id=1546069 hi mark, i can't find "live headers" extension for FF. so i can't provide you the header info....:( BTW thank for your help... r u still in aust.?? (almost 7:30pm now...:( ) ---------------------------------------------------------------------- Comment By: cheeng shu chin (cheengshuchin) Date: 2006-10-23 10:52 Message: Logged In: YES user_id=1546069 nope...non of them(I'm afraid).... actually we can POST file to iis server via "enctype='multipart/form-da". and we can read it out via isapi ecb.AvailableData, ecb.ContentType and with total bytes size ecb.TotalBytes. then we can use cgi module parse it after inject some isapi vars to os.enviroment(to make it become seem like CGI). Then I can expost all info in XML form via 4suit....:) I try to find "live headers" and try it again....:) ---------------------------------------------------------------------- Comment By: Mark Hammond (mhammond) Date: 2006-10-23 10:37 Message: Logged In: YES user_id=14198 I'm afraid I don't know how ISAPI is supposed to handle post data. You said you can't get the 'advanced' sample working - do any of them work? Maybe try the 'live headers' firefox extension - it may give you more clues what is going on. ---------------------------------------------------------------------- Comment By: cheeng shu chin (cheengshuchin) Date: 2006-10-23 10:26 Message: Logged In: YES user_id=1546069 I try to dig further, found that ECB seem work and recieve post data, even i can redirect those data to win32traceutil window include http vars or "print >>ecb, data", but it always end out with "The page cannot be displayed" for IE and "server connection reset" for firefox. ......???????!!!!!....:) ---------------------------------------------------------------------- Comment By: cheeng shu chin (cheengshuchin) Date: 2006-10-23 10:13 Message: Logged In: YES user_id=1546069 hi mark, thank for your fast respond.....:) nothing in win32traceutil window(except "Tester dispatching ******"). i had try "advanced.py" as well, seem not work....
