I'm using Axis 1.3 release and it looks like there is a problem when using compression. First, let me describe the scenario that I'm using:
1. I'm using axis to interact with SalesForce (http://www.salesforce.com/developer/)
2. I'm using compression (by setting HTTPConstants.MC_GZIP_REQUEST and HTTPConstants.COMPRESSION_GZIP to true)
3. I'm sending Authentication request tu URL1 (compressed) and sforce is providing the response NON-compressed. After this, HTTP connection is returned correctlyy to connection pool.
4. SForce is providing a new URL (URL2) for the subsequent HTTP requests within the context of this session.
5. Now, I'm sending the nex t SOAP request (a query for example). After receiving the response (this time SForce sent it compressed) I noticed that the connection is NOT returned to connection pool.
6. I'm sending another SOAP request and response is received correctly, b ut the HTTP connection is NOT returned to the connection pool again (response was aagin compressed).
7. Attempting to send another request will block the client since there are no connections left in the connection pool and the client will wait until a connection will eventually be returned to the pool. (default number of connections per host is 2)
After debugging a bit Commons Http Client code, it seems that GZIPInputStream doesn't really work very well with AutoCloseInputStream. What I mean is that AutoCloseInputStream monitors when end of stream is reached (read value == -1) and will automatically cause the connection to be returned to connection pool. When using GZIPInputStr eam this does not happen. AutoCloseInputStream is not "notified" (never reads -1) when GZIPInputStream reached the end of stream.
