> Key: HTTPCORE-361
> URL: https://issues.apache.org/jira/browse/HTTPCORE-361

> Priority: Minor

> The current implementation of getFirstHeader()
> public Header getFirstHeader(final String name) {
> for (final Header header : headers) {
> if (header.getName().equalsIgnoreCase(name)) {
> return header;
> }
> }
> return null;
> }
> uses a Java syntax that creates an iterator object for eac hcall. We are seeing a lot of those in heap dumps. The getLastHeader() method uses a loop and has no such problems.
> We realize that it is slightly less elegant, but it would be great if you could change this method into
> public Header getFirstHeader(final String name) {
> final int size = headers.size();
> for (int i = 0; i < size; i++) {
> final Header header = headers.get(i);
> if (header.getName().equalsIgnoreCase(name)) {
> return header;
> }
> }
> return null;
> }
