Project that demonstrates the issue

User-Agent:       Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/534.24 (KHTML,
like Gecko) Chrome/11.0.696.50 Safari/534.24

I've been trying to implement proper HTTP caching and compression for a project
that uses VirtualPathProvider to provide content. In Application_BeginRequest I
install Filter to HttpResponse (this filter is used to calculate ETags and
compress data), but this filter is getting only first 64Kb of data (the rest of
data comes straight into output past my filter).

I've made a small project that reproduces this problem and a patch that fixes
this issue for me (though I'm not sure whether it's OK in all cases).

Reproducible: Always

Steps to Reproduce:

1. Open the attached project in monodevelop
2. Run the project
3. Run in terminal:
curl http://localhost:8080/asd.txt 2>/dev/null | gunzip | wc -c
Actual Results:  
The following is printed to stdio:

gzip: stdin: decompression OK, trailing garbage ignored
65535

Expected Results:  
The following is printed to stdio:
