[jira] [Resolved] (HTTPCLIENT-1248) LaxRedirectStrategy converts POST to GET and throws away body

     [ https://issues.apache.org/jira/browse/HTTPCLIENT-1248?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Oleg Kalnichevski resolved HTTPCLIENT-1248.
-------------------------------------------

       Resolution: Fixed
    Fix Version/s: 4.2.2

@Jon
You are right. Redirects with 307 should not be converted to GET. I fixed the issue in both trunk and 4.2.x branch. Please review.

> The LaxRedirectStrategy extends the DefaultRedirectStrategy. The DefaultAsyncRequestDirector calls _redirectStrategy.isRedirected()_ and LaxRedirectStrategy will return *true* on a POST. Then the director calls _redirectStrategy.getRedirect()_. The LaxRedirectStrategy doesn't implement this method so the one in the DefaultRedirectStrategy is called:
> {code}
>         if (method.equalsIgnoreCase(HttpHead.METHOD_NAME)) {
>             return new HttpHead(uri);
>         } else {
>             return new HttpGet(uri);
>         }
> {code}
> This turns the POST into a GET on redirect. IMHO the LaxRedirectStrategy should be
> {code}
>     public HttpUriRequest getRedirect(
>             final HttpRequest request,
>             final HttpResponse response,
>             final HttpContext context) throws ProtocolException {
>         URI uri = getLocationURI(request, response, context);
>         String method = request.getRequestLine().getMethod();
>         if (method.equalsIgnoreCase(HttpHead.METHOD_NAME)) {
>             return new HttpHead(uri);
>         else if (method.equalsIgnoreCase(HttpPost.METHOD_NAME)) {
>             return new HttpPost(uri);
>         } else if (method.equalsIgnoreCase(HttpGet.METHOD_NAME)) {
>             return new HttpGet(uri);
>         } else {
>             throw new IllegalStateException("Redirect called on un-redirectable http method: " + method);
>     }
> {code}
