POST requests arrive late to ISAPI

Hi,

I have an ISAPI application running in IIS 5 and 6. For each POST
request, HttpExtensionProc starts a worker thread, and returns
HSE_STATUS_PENDING so it handle other requests.

Sometimes a of the worker threads does a long and busy task that might
take 1-2 minutes (e.g., read a 1GB file and caclulate its CRC).
In this case it first responds to the client and then does the long
task asyncronously.

I found that during this time, if the client machine sends a second
POST to this server using the same connection (open socket), ISAPI does
NOT receive this POST until the long operation is done.

I wonder why ISAPI does not receive the second POST, and if there any
way to fix it. The other POST are important for the client to know the
progress of the server's long operation.

Thanks in advance

You are right. I didn't call DONE_WITH_SESSION before starting the long
operation.
Now it's working fine.

Many thanks
