Hello,

First, sorry for my english, it isn't my native language.

I try to improve the WebDav module, and some requests are never read by nginx.

I have seen this bug on nginx-0.7.67 and nginx-1.1.0 (and I never try under other release).

Here is an extract from the output of tcpdump (the last PROPFIND request is never read by nginx) :

Current nginx autoindex module has hardcoded NGX_HTTP_AUTOINDEX_NAME_LEN constant. It makes sense to let user control it: nowadays, 50 characters are not enough to represent full file names. Moreover, I suspect UTF-8 names are getting twice lower limit of 25 characters.
